6.178

[Seng]zhao says: Having learned that the wholesome can be generated and the bad extinguished, he intends to relinquish both to seek the fundamental principle, and thus retroactively traces their root. [Dao]sheng says: Wholesome and unwholesome alternate as roots for each other, never being definitively settled. One must search out and contemplate their original source; only then can they be distinguished.
