俱舍論疏 5.12

5.12

[On the] Śāstra['s statement]: "Although the world does not understand … of what use would it be?": This is the third objection. The *Nyāyānusāra* explains: 'Generic similarity is not material form; how is it known to have function and to be able to produce distinct kinds of entities? It is known that it exists because its fruit is seen. Just as seeing the fruit obtained by karma in the present allows one to know that there was karma previously performed in a past life. Moreover, practitioners of contemplation directly realize and know it.'
