स्थितं प्रवृत्तं च तथा महाजनिकमेव च । त्र्यङ्गोत्त(ङ्गस्तु) स्यादथ द्व्यङ्गो महाजनिकवर्जितः ॥ २०२॥
The three limbs [of the Ullopyaka] is the Sthita, Pravṛtta and the Mahājanika. And the two-limbed [Ullopyaka] will exclude the Mahājanika, and the Mahājanika [only] will constitute the one-limbed [Ullopyaka].
