Tendai Lotus School Teachings, p 81Q: Craving and enlightenment, and delusion and awakening, are distinct. Is it not careless [to emphasize] the relative aspect of their meaning?
A: A distinction is made between delusion and awakening with regard to conditions, but since they are [fundamentally] unchanging, the essence of the defiled and of the pure are one. Therefore it is said that craving and enlightenment, and the cycle of birth and death and Nirvāṇa, are identical.
