SANKHĀRA
Although this word as used in the suttas has different specific references in different contexts, unlike dhamma it retains enough unity of meaning to permit, with rare exceptions, a uniform rendering. The problem, however, is to decide which of the many proposed renderings is the most adequate, or, if none are found fitting, to coin a new one that is.
The root idea suggested by the word sankhāra is "making together." The Pali commentators explain that the word allows for both an active and a passive sense. Thus the sankhāras are either factors (or forces) that function together in producing an effect, or they are the things that are produced by a combination of co-operating factors. In his translation of the Visuddhimagga Ven. Nānamoli had rendered sankhāras as "formations," a rendering favoured by many other translators. In his later translation scheme he had experimented with rendering it as "determinations" and had attempted to incorporate that new choice into his manuscript of the Majjhima. In editing the manuscript Ven. Khantipālo chose to return to the translator's earlier and better known "formations," and in this edition I have followed suit. Though this word has the disadvantage of accentuating the passive aspect of sankhāras, it avoids the problems into which "determinations" runs and seems colourless enough to take on the meaning determined by the context.
The word sankhāra occurs in four major contexts in the Pali suttas: (1) As the second factor in the formula of dependent origination it is used to mean volitional actions, suggesting their active role of generating results in the process of rebirth. (2) As the fourth of the five aggregates the sankhāras comprise all the mental factors not included in the other three mental aggregates; this group is probably assigned the name sankhārakkhandha after its chief member, volition (cetanā), which is responsible for forming all the other aggregates. (3) Sankhāra is also used in a very comprehensive sense to signify everything produced by conditions. In this sense it comprises all five aggregates (as at MN 35.4 and MN 115.12). Here the word bears the passive sense, being explained by the commentators as sankhatasankhārā, "formations consisting in the conditioned." This usage comes close in meaning to the ontological use of dhamma, except that the latter is wider in range since it includes the unconditioned element Nibbāna and concepts (paññatti), both of which are excluded from sankhāra. (4) In still another context the word sankhāra is used in relation to kāya, vacī, and citta - body, speech, and mind - to mean the bodily formation, which is in-and-out breathing; the verbal formation, which is applied thought and sustained thought; and the mental formation, which is perception and feeling. The first and third are things that are dependent respectively upon the body and the mind, the second the things that activate speech. This triad is discussed at MN 44.13-15.
Sankhāra is also employed outside these major contexts, and in one such case Ven. Nānamoli's sense of "determination" has been retained. This is where it occurs in the compound padhānasankhāra, which has been rendered "determined striving" (as at MN 16.26). The rare and involved idiom, sankhāram padahati, has similarly been rendered "he strives with determination" (MN 101.23). In another case (MN 120), following the commentarial gloss, sankhāra is rendered "aspiration."
