摩訶止觀 4.38

4.38

Furthermore, prātimokṣa means "guaranteed attainment of liberation"; contemplating the mind is also like this. If one does not contemplate the principle of the three truths, liberation from the three delusions is not guaranteed; if one sees the three truths, liberation from the three delusions is guaranteed. Such liberation liberates throughout the dharmadhātu, not stopping merely at liberation from the three destinies and emerging from birth and death.
