勸發菩提心集 3.75

3.75

Fourth, the pāramitās are only six in order to encompass the four causes of the Mahāyāna: first, non-defilement; second, supreme reverence; third, non-regression; fourth, non-discrimination. When cultivating dāna, one is not defiled by wealth, because one has no longing attachment. When receiving and upholding śīla, one gives rise to supreme reverence toward all the śikṣāpadas. When practicing kṣānti and vīrya, these two are non-regression: in kṣānti, one attains non-regression regarding the suffering caused by sentient and non-sentient beings; in vīrya, one attains non-regression when practicing the good. When practicing dhyāna and prajñā, these two are non-discrimination, because śamatha and vipaśyanā are equally gathered.
