JAINA THEORIES OF REALITY AND KNOWLEDGE
ductive agent in turn, a further productive agent and so on. See U in VD, p. 350, where Sankara Miśra repudiates the views that samavāya is other-caused or self-caused and affirms it is uncaused. See also TS, Notes, p. 97, SP, Notes, p. 6, and RML, pp. 148-149. The relata are, of course, said to be produced and destroyed while the relation (samavāya) is intact. samavāyas-tveka eva, TS, p. 6, sec. 8 and SP, p. 5 (text), kā. 9; sarvatraikaḥ samavāya iti gamyate, PB, p. 697; na ca samyogavan nānåtvam, ibid., p. 696; PBTS, with KR, p. 172.
The absolute oneness or sameness of samavaya inevitably raises the question how it can avoid an 'intermixture of the categories' (padārtha-sankara) which would lead, for instance, cowhood to reside in men instead of in cows. To this the Vaišeşika replies that the distinctness of the categories is sustained by the difference of the substrata and their attributes (adhārādheya-niyamāt); nanu yady ekaḥ samavāyo dravyaguņakarmaņām dravyatvaguņatvakarmatvādiviseşanaiḥ saha sambandhaikatvāt padārthasankara-prasanga iti, na adhārādheyaniyamat (PB, P. 697; see also U on VD, VII. 2. 26, and cf. SM, p. 32 (text), line 29, as well as the note on p. 81 (notes), lines 29-30), where reference is made to different media or avacchedakas of samavāya.
The unique character of samavāya, corresponding to the substantiality (dravyatva) of substance (dravya) or to the attributeness (guņatva) of attribute (guņa), etc., is the cognitive pattern "this subsists in that” (ihedam-pratyaya. or iheti-pratyaya-darśana). This pattern or mark is said to be the invariable feature of samavāya and, therefore, to denote the unity (oneness) or the sameness of samavāya in the diverse situations of its occurrence. See PB, p. 696.
The other important considerations adduced in support of the oneness of samavāya are 'economy' (läghava) and lack of evidence to the contrary: yathā dravyar sat gunaḥ sat karma sadityekākārapratītivişayatvāt nānātvasādhakapramāņābhāvāt lāghavāc ca sattā ekā, tathā ghataḥ samavetaḥ patah samaveta ityādy-anugatapratītivişayatvāt bhedakapramānābhāvātlāghavāc cn samavāyopyeka evetyarthaḥ / Von U, VD, p. 35,
