What This Concept Is Saying

Before we translate the term, we should pause on it. *Vaśitā* in Sanskrit carries the sense of mastery, sovereignty, having things in hand — it is the same root behind the Buddhist technical term "如意自在" (cintā-maṇi-ratna / wish-fulfilling jewel-like freedom) and behind the bodhisattva's ten *vaśitā* (十自在, the ten sovereignties of a bodhisattva). *Abhijñā* is "penetrating knowledge," and in the standard abhidharma list it names the six supernatural powers (六通). So the compound as a whole — translated here as 自在神通 (Sovereign Spiritual Powers) — sounds, on the surface, like it belongs to the technical catalogue of miraculous attainments: flying, clairvoyance, knowing others' minds, remembering past lives, and so on. The text we are reading, 《古尊宿語錄》 (Records of the Ancient Worthy Monks, a Chan/Zen anthology compiled in the Song dynasty), refuses that surface reading and replaces it with something far stranger.

The text states the matter directly: 「須信自在神通,彼此性真,妙具萬物,總非斷滅。」 ("You must trust in sovereign spiritual powers: both self and other have true nature, wondrously encompassing all things, and never falling into the view of annihilation.") The grammar of this sentence matters. It does not say "you must cultivate" or "you must attain." It says "you must *trust*" (須信). Sovereign spiritual powers are something one agrees to credit, not something one produces. And the reason one should credit them is not because they look impressive, but because the alternative is 斷滅 — the annihilation view, the conviction that underneath appearances there is nothing, that we are bare biological machines ticking toward extinction.

The phrase 「彼此性真,妙具萬物」 — "both self and other, true in nature, wondrously containing all things" — is doing two jobs at once. First, it extends the claim from "my own true nature" to "your true nature too." This is not a private mystical attainment; it is built on the prior insight that all beings share the same nature (性真). Second, it claims that this true nature is not bare or empty in a sterile way — it is 妙具萬物, wonderfully equipped with all things. This phrasing is a deliberate counter to the misunderstanding that "true nature is empty, therefore nothing matters." The Chan teaching, even in its most emptified formulations, refuses the nihilistic reading. Emptiness here is *fullness* of capacity, not vacancy.

The text immediately issues a warning to monastic practitioners: if you pursue enlightenment *outside* of this inherent nature, you are 「棄本逐末」 — abandoning the root to chase the branches. This warning fixes the orientation of the whole concept. Sovereign spiritual powers are not the goal of spiritual practice. They are what is already the case when you stop seeking them externally. The verb "to seek" is the disease; "to trust what is already present" is the cure.

The classical source then unfolds the same concept through three connected formulations, each doing distinct work. I want to be careful not to collapse them into one, because the text itself insists they are three lenses on the same thing.

Formulation One — 自在神通 (Sovereign Spiritual Powers): the foundation. This is the term in its purest form, used to fix the ontological point: the power is 本具 (inherently possessed) and 不可外求 (cannot be sought externally). It defines what the text is *not* talking about — displayable, cultivable, saleable, exotic tricks — and what it *is* talking about: the unimpeded functioning that belongs to true nature as such. The orientation here is corrective. It cuts against the seeker's habit.

Formulation Two — 如意自在 (Mind-at-Will Sovereignty): the manifestation. Here the text moves from foundation to appearance. Sovereignty appears through three layered non-obstructions (三重無礙), each of which is given its own expression:

- 色空無礙,如意自在 — "form and emptiness unobstructed, mind-at-will sovereign." All the myriad phenomena (萬象森羅) appear like reflections, inwardly and outwardly, and one can move at will between here and elsewhere. The point is not travel; it is that the boundary between "form" (matter, sensation, the concrete) and "emptiness" (openness, the unconditioned) is not a wall. - 理事無礙,如意自在 — "phenomena and principle unobstructed, mind-at-will sovereign." The text gives the image 「倒把須彌,卓向纖芥」 — "turning Mount Sumeru and thrusting it into a fiber-tip." This is the famous Chan compression of the universal into the infinitesimal and vice versa. The point is that principle (理, the abstract truth) and phenomena (事, the concrete case) are not two regions to be traveled between; they interpenetrate. - 事事無礙,如意自在 — "every-phenomenon-with-every-phenomenon unobstructed, mind-at-will sovereign." This is the deepest level and receives the densest imagery: 不動道場而遍及十方世界 (without stirring from the seat of awakening, pervading all ten directions), 東涌西沒而現千差萬怪 (rising in the east, setting in the west, manifesting myriad wonders), 「拈起一毛,重重法界;一念遍入,無邊剎海」 ("pick up a single hair — realm upon realm; one thought pervades — infinite oceans of lands"). This is the place where the text approaches, without naming it, the Huayan (Avataṃsaka) vision of 事事無礙 (the non-obstruction of phenomena with phenomena) — that famous image of Indra's Net where each jewel reflects every other jewel. The Chan text knows the Huayan vocabulary but delivers it in poetic compression rather than systematic doctrine.

Formulation Three — 神通並妙用 (Spiritual Powers together with Wondrous Functioning): the integration. Here the register shifts. The cosmic imagery of "picking up a hair, realm upon realm" gives way to the most ordinary scene imaginable: 「迎送及攀陪」 — "greeting, sending off, accompanying." The line that captures this most directly is 「更不假人教,自然隨事來」 — "no longer needing to be taught by another, naturally following what the matter brings." The teaching then closes with the verse 「幻身同草木,淨性出塵埃;迷頭總喚迴」 — "the illusory body is like grass and trees, the pure nature emerges from the dust; the lost head is always called back."

I want to highlight the closing image. 迷頭總喚迴 is a reference to the parable of the man running through the streets calling "Look for my head! Look for my head!" while his head is sitting calmly on his shoulders. The whole point of the concept is that we are the man in the parable. Sovereign spiritual powers are what is "on our shoulders" — already attached, already operating — while we frantically run around looking for them. The "calling back" is what the teaching does: it stops the running.

To hold the three formulations together: 自在神通 names the foundation (essence, 體); 如意自在 names the appearance (相), unfolding through three layered non-obstructions; 神通並妙用 names the functioning in daily life (用). Body, appearance, function — the standard Chan structure. The three are not stages to climb through; they are three faces of the same fact.

This is what makes the concept different from the standard abhidharma treatment of the six supernatural powers (六通 — 天眼通, 天耳通, 他心通, 宿命通, 神足通, 漏盡通). Those are yogically cultivated attainments. They are *about* the practitioner gaining capacities they did not have. The Chan concept inverts the grammar: the capacities were never absent; what is being gained is the recognition that they were never absent. The most pointed line of contrast comes from the warning: 「外道」 (non-Buddhist paths, or any path) that 預作示現 (pre-meditatedly displaying wonders) is precisely what this teaching is *not*. Sovereign spiritual powers unfold *naturally with circumstances* (自然隨事); they are not stage magic.


A Walk-Through in Everyday Life

Let's take the concept onto the ground. I'll walk through three scenes — common ones — and try to map each of the three formulations carefully. Most contemporary readings of Buddhist ideas fail because they collapse the structure into a single platitude; I want to keep the three formulations distinct so you can see what each one is actually for.

Scene One — The Meditation App Trap

You have been meditating for fifteen minutes a day for three months using a well-designed app. The app tracks your "streak," rewards consistency, offers courses on "unlocking" deeper states. Somewhere in the back of your mind, there is a quiet assumption: *if I keep doing this, something will unlock — insight, calm, maybe even the kind of thing the Buddha is reported to have had.* You do not say this out loud, even to yourself. But it is there.

This is the precise situation Formulation One (自在神通) is aimed at. 「棄本逐末」 — abandoning the root to chase the branch. The "root" here is not the app, the breath, the cushion, or the streak. The root is the fact that the awareness you are trying to *cultivate through* the app is the very awareness *with which* you would notice that you were trying to cultivate it. The text says you do not need to go outside yourself to find the sovereign functioning; the very "going outside" is the obstacle. This is not an argument against practice. It is an argument against the *orientation* that locates what you are looking for *somewhere ahead of where you are*. The app can be useful; the assumption that *it* delivers the goods, rather than *what you already are*, cannot.

Where most contemporary readers map this wrong: they hear "already complete" and conclude "no practice needed." That is the opposite error. The text is correcting the seeker who has externalized the goal, not the practitioner who is sitting down. 「不可外求」 means "cannot be sought externally," not "cannot be engaged with at all." The hard distinction is between *seeking the goal outside* and *engaging the path*.

Scene Two — Knowing What to Do, Not Doing It

It is 11 p.m. You have a deadline tomorrow. Your partner is asleep. You have read the productivity literature. You understand the neuroscience of procrastination. You can articulate, in precise terms, why scrolling your phone at midnight is not what you want to be doing. You also cannot stop.

Here is the gap that the second formulation (如意自在) is built to address — specifically, the layer called 理事無礙 ("phenomena and principle unobstructed"). The principle (理) you carry in your head is clean: "I should sleep, not scroll." The phenomenon (事) you are living — body in chair, thumb moving, attention dissolving — does not consult the principle. They are two separate regions in your experience: the abstract truth and the concrete case, with a wall between them. You have 理 (the principle), but you do not have its 融通 (permeation into) the 事.

The Chan text does not promise that the wall will vanish through more reading, more willpower, or another framework. The image 「倒把須彌,卓向纖芥」 ("turning Mount Sumeru and thrusting it into a fiber-tip") is meant to short-circuit the assumption that principle and phenomenon are large and small versions of *different things*. They are large and small versions of *the same stuff*. The finger that scrolls and the mind that knows it should not be scrolling are not in different ontologies. They are the same ontology at different scales. To recognize this is not to solve procrastination; it is to stop being a stranger to your own midnight hour.

Where readers map this wrong: they take the brilliant Huayan-style imagery as a metaphysical poem about cosmic unity and miss that it is a description of what *happens* (or fails to happen) in your hand at 11 p.m. 「一念遍入,無邊剎海」 — "one thought pervades — infinite oceans of lands" — is not a doctrine about the universe; it is a description of what one *fully present* moment contains.

Scene Three — The Loss at the Dinner Table

You are at dinner with people you love. Your phone is face-down. You have told yourself, sincerely, that tonight you will be present. Three minutes in, the conversation has not delivered the "deep" moment you were hoping for. Someone repeats a story you have heard. You feel the familiar pull — not toward the phone, but toward a slight inner judgment of *this is not it*. The presence you wanted was supposed to feel like something. It is feeling like nothing. The dinner, suddenly, feels like a missed opportunity. You leave the table a little tired of yourself.

This is Formulation Three's (神通並妙用) exact terrain. 「迎送及攀陪」 — greeting, sending off, accompanying. 「更不假人教,自然隨事來」 — not needing to be taught by another, naturally following what the matter brings. The Chan's claim is that the *missing* thing you feel at the dinner table is itself the wrong frame. The presence you wanted to feel would have been another experience added on top of the dinner; the Chan's "wondrous functioning" is what happens when you stop trying to add experiences. The greeting, the response to the story, the offering of a dish, the silence while someone chews — these are the 神通並妙用. They do not need to be taught by anyone else, because they arise naturally when the moment is not being filtered through the demand that it be something other than what it is.

The closing verse 「幻身同草木,淨性出塵埃;迷頭總喚迴」 fits here. The illusory body that was disappointed in the dinner is like grass and trees — it had its moment and continues. The pure nature that emerges from the dust of the actual encounter is what you missed while you were evaluating the encounter. 迷頭總喚迴 — the head was always there; the running was the problem. The teaching's job is to call you back to what was always happening.

Where readers map this wrong: they treat this as a counsel of low expectations, of settling, of "just be present, bro." That reading strips the concept of its metaphysical depth and reduces it to a mindfulness cliché. The text is not saying "lower your standards." It is saying that the standards you are applying were never located in the place where you were looking for them. The dinner table did not lack presence; *you* lacked the recognition that presence was what the dinner table *was*.


Why Contemporary People Need This

I think there are three pressures in the present cultural moment that make this concept not merely interesting but genuinely necessary.

The first is the inversion of the relationship between capacity and sovereignty. We live inside an apparatus that keeps offering us new powers. Every year the devices in our pockets are more capable than the year before; every year the algorithms are better at predicting what we want; every year the tools we use to work are more powerful. Capability, in the contemporary era, has never been higher. Sovereignty — the felt experience of being the master of one's own attention, time, and inner life — has, by all available measures, never been lower. People report a kind of vertigo: I can do so much, and yet I feel so little ownership of what I do. The Chan diagnosis in this concept is precise. Power (capacity) and 自在 (sovereignty, mastery) are not the same thing. In fact, the relentless *addition* of capacity can mask the *loss* of sovereignty, because we mistake the experience of doing more for the experience of being more. The text's insistence that sovereign spiritual powers are 本具 (inherently possessed) and 不可外求 (cannot be sought externally) is, in our moment, almost a heresy against the dominant frame — which holds that whatever is missing in one's life is missing because one has not yet acquired the right tool, technique, retreat, app, or relationship.

The second is the way spiritual seeking has itself been colonized by the external-seeking habit. It is no longer the case, if it ever was, that Buddhist or contemplative practice sits outside the broader cultural pattern of optimization. People "do" mindfulness the way they "do" cardio — for measurable outcomes, for the streak, for the biohacked result. The retreat industry packages the unconditioned as a five-day experience. The teaching apps gamify what the text insists cannot be sought externally. Formulation One (自在神通) is aimed, in our moment, not at the rare mystical seeker but at the much larger population of *spiritual consumers* who have mistaken consumption for practice and configuration for realization. The 「棄本逐末」 — abandoning the root to chase the branch — is, today, the entire spiritual marketplace. The text's warning is therefore not archaic. It is surgery on the present moment.

The third is the way contemporary life fragments the layers that this concept holds together. Most of us live in conditions that are excellent at 色空無礙 (form-emptiness non-obstruction) being violated. By that I mean: we treat the world of forms (the phone, the inbox, the news cycle, the bodily sensation, the other person) as solid, separate, demanding; and we treat the "emptiness" that we half-remember from some meditation or reading as a separate region to be visited occasionally. The two regions never meet. We have a work-self and a meditation-self and a relationship-self and a Sunday-mountain-self. These selves are all forms of avoiding the radical fact that awareness is doing all of it. The concept's insistence on three layered non-obstructions — form-emptiness, principle-phenomenon, every-phenomenon-with-every-phenomenon — is, in our moment, a prescription for the re-unification of a self that has been split into experiential silos by the logic of optimization.

I should be cautious here. There is real contemporary research on attention, on the default mode network, on the way contemplative practices affect stress responses. I do not want to claim that science has *proven* the Chan teaching. What I want to say is something more modest: the cultural conditions in which the contemporary self lives — saturated with capacity, fragmented across contexts, habituated to external seeking — make the question of sovereignty (rather than capacity) the urgent spiritual question of our era. The Chan concept answers that question with a structure that no purely scientific account can match, because the structure is ontological rather than empirical. Whether or not the neurobiology lines up, the question of where to look for what is missing remains, and the concept's answer — *it is not missing; you are looking in the wrong direction* — is exactly what our moment most needs to hear.


Common Misreadings and Clarifications

Let me name the misreadings I see most often, and be specific about where each one goes wrong.

Misreading One: Treating 自在神通 as a synonym for supernatural display. This is the easiest mistake to make because the words seem to invite it. Surely *spiritual powers* means ESP, levitation, clairvoyance, the works. But the text is built to refuse this reading. The line 「不假人教,自然隨事來」 — "without being taught by another, naturally following what the matter brings" — is the opposite of display. Display is *for* an audience; it is staged; it is what the text calls 「預作示現」 (pre-meditated showing). What the text is pointing to is the *absence* of staging, the unobstructed response that arises in the moment without a script. If you meet someone who claims sovereign spiritual powers and they show you a miracle, the text is, ironically, telling you they have not understood the concept. The miracle would be the proof that they do not have it. This is a deep inversion and worth sitting with.

Misreading Two: Treating 本具 (inherently possessed) as license to skip practice. This is the second most common error, and it is structurally the mirror-image of the first. If someone says "I am already complete, so why bother practicing?" they have taken half of the teaching and used it to justify something the teaching explicitly forbids. The text does not say practice is unnecessary. It says that what practice is *for* cannot be sought outside the nature one already has. There is a vast difference between "I do not need to practice" and "I cannot find what I am practicing for by going outside." The first is laziness; the second is the actual teaching. The classical statement 「棄本逐末」 is a warning to practitioners, *not* to those who have decided they will not practice. Monastics receiving this teaching were already on the path; the warning was about the *direction* of the path.

Misreading Three: Confusing 自在神通 with the six abhijñā (六通) of abhidharma. In the standard Buddhist catalogue, 六通 lists six cultivated supernatural powers: 天眼通 (clairvoyance), 天耳通 (clairaudience), 他心通 (knowledge of others' minds), 宿命通 (knowledge of past lives), 神足通 (psychokinesis/flight), 漏盡通 (extinction of contaminants). These are cultivated attainments, fruits of deep samādhi. The Chan concept of 自在神通 shares some vocabulary but inverts the grammar. The six powers are what the practitioner *gains* through extraordinary concentration. The sovereign spiritual powers of this concept are what the practitioner *recognizes* were never absent. The text's contrast with 「外道預作示現」 (non-Buddhist or heterodox pre-meditated display) is the clue: the entire orientation is away from cultivation-of-the-exotic and toward recognition-of-what-is-already-so. There is also a doctrinal reason for the inversion: the Chan tradition, following certain strands of the Prajñāpāramitā and Tathāgatagarbha literature, holds that the capacities described by the six powers are functions of awareness *as such*, not additions to awareness. They are not built; they are seen.

Misreading Four: Treating 如意自在 as "doing whatever I want." The Chinese character in 自在 is often misread as "self" — and "doing what one wants" becomes the trivial translation. But the word points to from oneself, *spontaneously*, *without external compulsion*. In the text, this means the response arises from the true nature, not from the reactive ego. There is a critical difference between "doing whatever I want" and "acting without obstruction." The first is the fantasy of the ego in a state of unlimited indulgence; the second is the responsiveness of a nature that no longer meets resistance in the moment. 「迎送及攀陪」 — greeting, sending off, accompanying — is given as the example. These are *other-oriented* responses. The "wants" of the ego are precisely what the text is asking one to stop trusting as the source of action.

Misreading Five: Treating the Huayan-style imagery as merely poetic. The lines 「拈起一毛,重重法界;一念遍入,無邊剎海」 sound like mystical hyperbole. If they are taken as metaphors about cosmic unity, they dissolve into pleasant vagueness. But the text does not present them as metaphors. They are presented as descriptions of 示現 — manifestations. The "single hair" is not a metaphor for the universe; it is, in the moment of attention, the universe as such. The "one thought" pervading "infinite oceans of lands" is not a claim about ontology in the abstract; it is a description of what attention actually does when it is not contracted. To dismiss this as poetry is to miss the entire weight of the teaching. (To be precise about sources: the Huayan / Avataṃsaka tradition — the 80-fascicle and 60-fascicle recensions of the 《華嚴經》, along with treatises like the 《華嚴經探玄記》 by Chengguan — develops this vision systematically under the headings of 理法界 / 事法界 / 理事無礙法界 / 事事無礙法界 (the Four Realms of Dharma). The Chan text alludes to this without building the doctrinal architecture; the reader who knows the Huayan context will hear more in the imagery, but the meaning is not dependent on that background.)

Misreading Six: Treating the closing verse 「迷頭總喚迴」 as a gentle reassurance. "The lost head is always called back" can sound like a comforting promise — don't worry, you won't actually lose yourself, the teaching will catch you. That reading turns the verse into a sedative. The parable is sharper than that. The man in the parable is not in danger; he is in *embarrassment*. The whole street is watching him run around with his head perfectly on his shoulders. The "calling back" is not rescue; it is *the moment of seeing*. It is the moment you notice that what you were running to find is what is running. The teaching is not gentle. It is slightly embarrassing, and the embarrassment is part of what makes it effective.


If I had to compress what this concept is *for*, I would say: it is the surgical correction to the most modern of habits — the habit of treating what is happening *inside* the present moment as if it were somewhere *ahead* of the present moment. The sovereign spiritual powers that the 《古尊宿語錄》 invokes are not the glittering capacities of a perfected being. They are the recognition, repeatedly lost and repeatedly recalled, that the awareness with which you search is itself what you are searching for. The head is on the shoulders. The presence is at the dinner table. The principle is in the phenomenon. The realm-on-realm is in the single hair.

And — this is the part that I want to leave you with, because the Chan text insists on it — the calling back (迷頭總喚迴) is *not a once-and-for-all event*. The text does not say "you will recognize this once and be done." It says the head is *always* being called back, because the running is what minds do. 自在神通 is not a state to attain. It is the unceasing return to what was never lost. The practice, if there is one, is the willingness to be called back again.

定义与核心要义

自在神通(vaśitābhijñā),指本性真实、妙具万物之任运无碍妙用,本具而不可外求。此词于《古尊宿语录》中作为禅家所体证之神通而与「如意自在」「神通并妙用」诸语相连而立,其核心在于破除外求之执,显示性真本具、随缘无碍、日用自然三义。

主要阐述

《古尊宿语录》论「自在神通」,首揭「须信自在神通」一语,以「彼此性真,妙具万物,总非断灭」明其根本:此神通非离当下一念本性而另得的奇特伎俩,乃彼此本性真实,于妙用中具足万物,同时不落于断灭之见。本经随即警策衲僧:若于本分事之外别求禅悟,便是「弃本逐末」——神通之自在本于性真,不待外驰而得。

本经又以「如意自在」一语,从多重无碍层面展开其示现。「色空无碍,如意自在」一层,万象森罗皆如影显现于内外,可出没往来于此土、他界;「理事无碍,如意自在」一层,以「倒把须弥,卓向纤芥」等语呈现大小互摄、理事融通之境。更突出的表述是屡称「事事无碍,如意自在」,其示现包括不动道场而遍及十方世界、东涌西没而现千差万怪,乃至「拈起一毛,重重法界;一念遍入,无边刹海」。此等语句将自在写成于目前「或显或晦」、于一毛一念中重重遍入的无碍作用,并以火中虫物、街头布袋及日常行止等反常意象,显示其不受固定形相拘碍的侧面。

另有段落不再连称「自在神通」或「如意自在」,而以「神通并妙用」表述,强调其落实于「迎送及攀陪」等寻常应对之中。其关键在「更不假人教,自然随事来」——妙用不待他人教授或预先造作,乃因事自然呈现。承以「幻身同草木,净性出尘埃」,于幻身与净性之对照中收束于「迷头总唤回」的回转迷失之旨。

不同部类与译本的表述差异

本经关于此概念主要采用三种相连而各有侧重的形式,兹列如下:

一、「自在神通」:侧重性真本具、不可外求之义,对治「弃本逐末」之见。 二、「如意自在」:与「色空无碍」「理事无碍」「事事无碍」连用,侧重遍现、融通、无碍之境。 三、「神通并妙用」:侧重日用应事中自然发用,不假教、不预造。

三者并行而不相悖:前者明体,后二者明用;体用相即,方是本经所诠自在神通之全貌。需注意者,本经并无同经异译本之分歧,三种表述乃同一禅录中依不同语境而展开之侧面。

与相关概念的关系

「自在神通」与「如意自在」「神通并妙用」在本经中互为表里——「自在神通」标其本体不可外求,「如意自在」显其事事无碍之相,「神通并妙用」示其日用自然之功。三者同以「性真」为根,以「无碍」为相,以「自然」为行。

又,本经所论之神通迥异于外道预作示现之神通,乃以「不假人教、自然随事」为其特质,故与「断灭」「外求」「预造」诸边见相对而立。至于华严事事无碍「一即一切、一切即一」之境界,与本经「拈起一毛,重重法界」之表述,于重重遍入义上相通,然本经以禅家机语出之,不作教理之系统建构。

代表性原文引用

- 「须信自在神通,彼此性真,妙具万物,总非断灭。」 - 「色空无碍,如意自在。」 - 「理事无碍,如意自在。」 - 「事事无碍,如意自在。」 - 「拈起一毛,重重法界;一念遍入,无边刹海。」 - 「神通并妙用,迎送及攀陪。更不假人教,自然随事来。」 - 「幻身同草木,净性出尘埃;迷头总唤回。」

古尊宿語錄X1315 · 禪宗語錄部

《古尊宿語錄》論「自在神通」,首先直稱「須信自在神通」,並以「彼此性真,妙具萬物,總非斷滅」說明其根本:自在神通不是離開當下性真而另得的奇特能力,彼此本性真實,妙用之中具足萬物,亦不落於斷滅。原文隨即警策衲僧,若在本分之外另求禪悟,便是「棄本逐末」;因此,此處的神通著重本具、自然而無須外求。

本經又反覆使用「如意自在」一語,從多重無礙展開其示現。先說「色空無礙,如意自在」,萬象森羅皆能如影顯現於內外,且可出沒往來於此土、他界;繼而說「理事無礙,如意自在」,以「倒把須彌,卓向纖芥」等語呈現大小互攝、理事融通的自在境界。

更突出的表述是屢稱「事事無礙,如意自在」。其示現包括不動道場而遍及十方世界、東涌西沒而現千差萬怪,也包括「拈起一毛,重重法界;一念遍入,無邊剎海」。這些語句把自在寫成於目前「或顯或晦」、於一毛一念中重重遍入的無礙作用;文中又以火中蟲物、街頭布袋及日常行止等峻烈而反常的意象,呈現其不受固定形相拘礙的側面。

在另一段中,本經不再連稱「自在神通」或「如意自在」,而用「神通並妙用」表述,並說它落實於「迎送及攀陪」等尋常應對。其關鍵是「更不假人教,自然隨事來」:妙用不待他人教授或預先造作,而是因事自然呈現。原文又以「幻身同草木,淨性出塵埃」相承,指出幻身與淨性之間的對照,最後以「迷頭總喚迴」收束於回轉迷失。

就用詞而言,本經關於此概念主要採用三種相連而各有側重的形式:「自在神通」著重性真本具而不可外求;「如意自在」與「色空無礙」「理事無礙」「事事無礙」連用,著重遍現、融通及無礙;「神通並妙用」則著重日用應事中的自然發用。三者共同呈現的核心,是本具而非斷滅、隨事而不假教、於萬象與十方中任運顯晦的神通妙用。
