一、这个概念在说什么
At first glance, the term "業差別" (karma-prabheda, "distinction of karma") most naturally leads one to think along the lines of good karma and bad karma, defiled and pure karma, conditioned and unconditioned karma—this is the most reflexive association, because the most common collocation of "業" (karma) in Chinese Buddhist contexts is property-based classification. But once that association arises, it must be held in check: when placed back into its original position in the *Mahāyānasūtrālaṃkāra* (*大乘庄严经论*, T1604), one encounters a rather different structure.
業差別 (karma-prabheda) is not a standalone term for classifying the properties of karma; it is one of six aspects of observation under the larger concept of 精進 (vīrya, "vigor" or "diligence"). The root text establishes its outline in verses:
勝因依業種，對治等異故。
Six characters—"胜、因、依、业、种、对治"—are a condensed summary of six analytical angles. The subsequent commentary expands these six characters into their full designations: "勝差別 (distinction of superiority), 因差別 (distinction of cause), 依止差別 (distinction of basis), 業差別 (distinction of karma), 種差別 (distinction of type), 對治差別 (distinction of antidote)." 業差別 (karma-prabheda) ranks fourth, following 依止差別 (āśraya-prabheda, "distinction of basis") and preceding 種差別 (gotra-prabheda, "distinction of type").
This raises a fact that must be stated clearly at the outset: the specific content of 業差別 (karma-prabheda), in the present quotation of this general summary verse, is only "given a name"—it is not elaborated. The commentary itself states this plainly—"此偈總舉，餘偈別釋" ("this verse gives the general enumeration; subsequent verses explain each item separately")—and there should follow further verses providing item-by-item explanations, but that portion of the original text is not in our possession. Thus, as far as the presently cited textual material is concerned, what can be established is 業差別's "position" and "structural relations" within the system of diligence distinctions—not its definitional content. The root text also does not enumerate wholesome or unwholesome karma-types, nor does it contain any explicit passage linking these six distinctions to the classification of good and evil. Any reading that directly inserts property-based oppositions such as "wholesome karma / unwholesome karma / neutral karma" into 業差別 oversteps the boundary of the text.
That said, the designation "業差別" still has three layers that can be discussed, because the designation itself carries semantic weight.
First layer: position. 業差別 belongs to a larger analytical system. It does not deal in isolation with "which karma is good and which is bad," but rather uses the angle of "karma" to observe what distinctions the same object—精進 (vīrya, "diligence")—manifests. 勝差別 views it from the highest aspect of sphere or principle, 因差別 from the cause on which it depends, 依止差別 from that on which it rests, 種差別 from its categories, 對治差別 from its function of counteracting afflictions—業差別 stands alongside these, meaning it provides another independent slice.
Second layer: literal meaning. The central character of the designation is "業" (karma). In Buddhist contexts, 業 (karma) generally refers to intentional acts of fabrication—encompassing bodily karma, verbal karma, and mental karma. When "業" (karma) functions as an analytical angle applied to 精進 (vīrya, "diligence"), then following the literal meaning, 業差別 should be concerned with the differences in how diligence manifests along the dimension of "action, fabrication, and doing": what kind of deeds one performs when being diligent, how the forms of those deeds differ, how that effort lands in specific bodily, verbal, and mental fabrications—this is a direction that can be reasonably inferred from Buddhist semantics, but it must be flagged as a reading-inference based on the semantic system, not a definition explicitly given by this portion of the root text.
Third layer: the boundary with 種差別. 種差別 does have verses with specific content in the root text:
因果及隨法，內外與麁細，勝劣亦遠近，是謂種差別。
Cause and effect, conformity with the Dharma, inner and outer, coarse and fine, superior and inferior, near and far—these six pairs of relative terms all belong to 種差別 (gotra-prabheda, "distinction of type"), not to 業差別. Transferring the content of 種差別 onto 業差別 is precisely the error the root text itself warns readers against ("不可將『種差別』的具體內容移作『業差別』的解釋" — "one must not transpose the specific content of 'distinction of type' as an explanation of 'distinction of karma'"). 業差別 and 種差別 appear side by side in the verse, each being an independent lens of observation.
In summary: what the term 業差別 truly tells us is this—when analyzing the matter of 精進 (vīrya, "diligence"), the dimension of "doing / fabrication" deserves to be set apart as its own cell for observation. As for the specific items within that cell, the present portion of the text has not yet stated them; they await the other explanatory verses.
二、生活里的走查
Since 業差別 in the root text is merely a "cell awaiting elaboration," a walkthrough in daily life resembles a demonstration of on-site observation: we use the angle of "what distinctions does diligence manifest in a person's concrete deeds" to scan ordinary life.
First, fix the object of observation: 精進 (vīrya, "diligence"). Diligence is not vague "effort" or "getting pumped up"; in Buddhist contexts, it refers to sustained valor toward what is wholesome, non-retreat from practice—a directed, committed application of effort. When this application of effort lands on those of us living in the contemporary era, its "acting" layer can manifest in several clearly different guises:
Guise one: action along the temporal dimension—"sustained action" versus "sprint action." Some people spread diligence out as daily routine—like sitting in meditation for half an hour every day over many years, reading scriptures weekly on a fixed schedule, regularly dedicating merit—the action is evenly distributed. Others compress diligence into sprints—New Year vows, quarterly pushes, year-end rewards and penalties—the action is highly concentrated. The former is the action of constant diligence; the latter is the action of galvanized diligence. The two have different curves of exertion; both land in life as "action," but their forms are extremely different—this is one observable distinction along the 業差別 dimension.
Guise two: action along the object dimension—"solitary action" versus "other-involving action." Reading scriptures alone on a weekend, organizing notes—that is diligence; patiently accompanying an elder through a knot in their heart—that is diligence; a colleague comes to confide in you after lunch, and you can resist reaching for your phone, listening quietly to the end—that is diligence. The former's action is directed at oneself; the latter's action is directed at others. Both are "striving toward the good," one settled in stillness, one settled amid disturbance—the structures of bodily and mental exertion are vastly different.
Guise three: action along the quality dimension—"action of barely pushing through" versus "action of dwelling within." Finishing the day's practice assignment even if it means pushing through to the early hours after overtime—that is diligence; feeling no hardship in it, but rather a sense of dwelling within—that is also diligence. From the outside both look like "persistence," but landing on the three karmas of body, speech, and mind, one carries the tugging sensation of affliction, the other carries joy and the power of aspiration. Along the 業差別 dimension, the mental factors (心所, caitta, "the companions of the mind") behind the fabrication are not the same, and the karmic forces thereby drawn forth naturally cannot be the same.
Guise four: action along the directional dimension—"action for oneself" versus "action for sentient beings." Striving vigorously to eliminate one's own karma, to attain awakening for oneself—the "acting" of this diligence is inward-facing; making vows for the benefit of others, persevering for the endurance of the true Dharma—the same "effort," yet the object of its action, its intention, and the degree of involvement differ greatly. This distinction is especially visible along the karma dimension: the "for whom is it done" of bodily, verbal, and mental fabrication profoundly changes the nature of that effort.
These four distinctions above—time, object, quality, direction—are not items explicitly given by the root text; they are possible slices derived by walking out the semantic axis of "fabrication / acting" carried by the character "業" (karma), applied to the object of observation that is 精進 (vīrya, "diligence"). They demonstrate the directions along which the position of 業差別 can be walked out once it lands in life; as for what items the root text's subsequent verses actually use, we must wait to see the original of the separate explanatory verses.
Here, let us promptly point out the places where most people misproject:
- Mistaking 業差別 as "the distinction between good karma and bad karma." This is the most common slippage. 業差別 belongs to the system of diligence distinctions, not to the system of karma-properties. Its "業" (karma) points to the perspective used when observing diligence; it is not about dividing diligence itself into good and evil.
- Mistaking the six pairs of 種差別 as belonging to 業差別. Cause and effect, conformity with the Dharma, inner and outer, coarse and fine, superior and inferior, near and far—these are explicitly assigned by the root text to 種差別. 業差別 is currently an empty cell; what fills it later depends on the separate explanatory verses—one may not make up the numbers with the items of 種差別.
- Mistaking 業差別 for a standalone practice method. It is not a method; it is one cell in an analytical framework. Its value in itself lies in indicating: there are multiple angles for observing diligence, and "acting" is one of them.
三、当代人为什么需要它
What contemporary people least lack is "effort"—overtime, commuting, childcare, replying to messages, fitness, language learning, self-media updates—each of these is a contemporary variant of 精進 (vīrya, "diligence"). The problem is that these efforts take vastly different forms, yet few people stop to ask: "Along the acting dimension of my effort, which kind does it actually belong to? What is the difference between it and other forms?"
The contemporary significance of 業差別 as an observational cell lies precisely in forcing us to slice and observe our own effort from the dimension of "action / fabrication." A common contemporary predicament is—our "diligence" has long been highly concentrated on the time axis (racking up online hours, completing KPIs, covering project counts), while the inner quality of "acting" (the harmony of mental factors, the direction of intention, the coordination of bodily, verbal, and mental fabrication) is severely imbalanced. Under the lens of 業差別, this imbalance is illuminated clearly: it is not that you lack diligence; it is that the action-structure of your diligence has tilted.
Introducing this observational cell into contemporary life makes at least three things possible:
First, bringing "effort" back to the concrete layer of fabrication for verification. Diligence cannot remain only at the feeling layer of "I am working so hard"; it must be checked against the concrete fabrications of the three karmas of body, speech, and mind. This is re-fastening the severely diluted word "effort" back to its original shape in Buddhist contexts.
Second, making the differences between efforts visible. Both persist in running for a year—one person pushes through with affliction, another dwells in bodily and mental ease—the karmic forces trailing behind the "acting" of these two efforts do not run in the same direction. Only when this difference is illuminated does adjustment become possible.
Third, maintaining the cognitive humility that "the cell of 業差別 has not yet been filled." Since the root text's explicit passages have not yet elaborated the specific items of this cell, contemporary readers have no need to rush to stuff contemporary classifications (habits, goals, flow, deliberate practice…) into it. Keep it in one's conceptual repertoire as an open observational perspective; when encountering specific scenes, walk it out with this dimension, which is closer to the root text's attitude than rushing to define it.
In the contemporary effort-environment, almost every week invents new efficiency theories and self-discipline frameworks. The contemporary value of 業差別 lies not in providing a new framework, but in offering an ancient reminder: any framework ultimately counts only when it lands in concrete fabrication. Observing the distinctions of "acting" is the ultimate way to observe whether any framework is genuinely taking effect.
四、常见误读与澄清
Misreading one: "業差別 = the classificatory distinctions of karma"
This is the most common and most dangerous misreading. Once 業差別 is read as "the classificatory distinctions of karma," it readily gets mis-filled with content such as "wholesome karma / unwholesome karma / neutral karma," "conditioned / unconditioned," "defiled / pure"—none of which has any basis in the root text. In this passage, the root text only lists 業差別 as one cell in the system of diligence distinctions, without any elaboration of property-based classification within it. 業差別 belongs to the distinctions of diligence, not to the classification of karma-properties.
Misreading two: "the content of 種差別 is the content of 業差別"
種差別 has specific verses in the root text: "因果及隨法，內外與麁細，勝劣亦遠近，是謂種差別." These six pairs of relative terms belong to 種差別, not to 業差別. The treatise itself already cautions—one must not transpose the specific content of 種差別 as an explanation of 業差別. 業差別 and 種差別 appear side by side in the verse; they are two lenses each with independent facets and cannot be superimposed.
Misreading three: "業差別 includes all matters contained in the character '業'"
The character 業 (karma) carries a vast amount of semantics in Buddhist contexts (the three karmas of body, speech, and mind; meritorious and non-meritorious karma; moving and still karma…). 業差別 does not automatically inherit the entire connotation of the character "業" across the whole Abhidharma system. Here the root text condenses it with the single character "業," later expanded as "業差別"—this "業" is used within the specific context of the distinctions of diligence, and its connotation should be constrained by that context; it cannot be infinitely extended.
Misreading four: "業差別 is an independent practice method"
It is not. It is part of an analytical framework. Treating it as a method leads one to seek "methods for cultivating 業差別"—this is a misplaced question. Its true position is that of a perspectival tool adopted when observing one's own or others' diligence. Tools are not "cultivated"; tools are "used."
Misreading five: "since the root text has not elaborated its details, 業差別 is an empty concept"
Although the present portion of the text has not elaborated specific items, 業差別 is not an empty concept. It carries at least two things: first, it confirms that the dimension of "acting / fabrication" deserves its own cell when analyzing diligence; second, it fixes the structural position of this cell relative to the other five cells (superiority, cause, basis, type, antidote). An observational angle with a fixed position and neighboring cells is not an empty concept structurally. It awaits completion, but awaiting completion is not the same as nothingness.
A final summary
What is most worth taking away from 業差別 is not a set of content items yet to be determined, but rather an angle of observation: when we face the matter of 精進 (vīrya, "diligence")—whether it be our own morning practice, another person's perseverance, or the various cultural narratives about effort—we can try switching to the dimension of "acting / fabrication," and see what form this effort actually unfolds into in body, speech, and mind, and how it differs from other forms at other periods of one's life.
The root text needed six cells to observe diligence thoroughly—this itself is a reminder: a single perspective cannot see the whole picture; the additional perspective is a position reserved for oneself, not superfluous knowledge. 業差別 is precisely one of those six reserved positions.
