________________ The Concept of Paryaya - Mode Rashmibhai Zaveri 1 Paryaya Defined 1.1 While discussing the nature of paryaya one must study about substance (dravya), its existence (sat), its attributes (guna) and its relation with modes (paryayas). Ganadhipati Tulsi has defined paryaya in "Illuminator of Jain Tenets" (II edition - 1995) as:- 1 "Purvottarakara parityagadanam paryayah (I-40)". Mode means forfeiture of the precedent (state) and appropriation of the succeeding state. This definition of paryaya must be read in context with that of substance (dravya). 1.2 Uttaradhyayana Sutra defines dravya, guna and paryaya in the sixth sloka of the twenty - eighth chapter called 'mokkhamaggagai as follows: "gunanamasao davvam egadavvassiya guna, lakkhanam pajjavanam tu ubhao assiya bhave." That which is the substratum of attributes (guna) is called substance (dravya). That which are resting on (only) one substance are called attributes or qualities (gunas). The characteristic (laksana) of a mode (paryaya) is that it rests both on substance as well as attribute or quality. Jaina Scholars have drawn heavily from this canonical pronouncement.
