Bhāsya 1. Sutra 132
In the Anuyogadvāru Sūtra four types of pramāna have been mentioned: dravya pramāna, ksetra pramāna, kāla pramāna, bhāva pramāna.' The kāla pramāna is of two kinds-pradeśa nişpanna and vibhāga nispanna. The starting point of vibhāga nispanna period is samaya (indivisible time-unit) and the last point of that period is pudgalaparāvartana (the time it takes all karmika particles to undergo their complete course of binding and falling from the soul). In the present dialogue, there is exposition of measurable (numerable) time. However, there is no mention of samaya there. The starting point of measurable time is samaya. See the following table: Samaya
= The ultimate indivisible unit of time Innumerable sumayas = One avalikā Numerable āvalikās = One exhalation Numerable avalikās = One inhalation One inhalation-exhalation = One prāna 7 prānas
= One stoka 7 stokas
= One lava 77 lavas or 48 minutes One muhūrtta 30 muhurttas
= One day and night 15 days and nights = One fortnight 2 fortnights
One month 2 months
= One rtu 3 rtus
One solstice 2 solstices
=' One year 5 years
= One yuga 20 yugas
= One hundred years 8400000 years
= One pūrvānga 8400000 pūrvāngas = One purva = 8400000 x 8400000 =
70560000000000 years 8400000 pūrvas
= One truțitānga From truțitānga upto sirsaprahelikā, each succeeding number is obtained by multiplying the preceeding number by 8400000. Thus calculated, the sirsaprahelikā comes to be the number—-758263253073010241157973569975696406218966848080183296 with 140 zeros appended to it. The whole number consists of 194
