Note f33 — ZEN AS CHINESE INTERPRETATION OF THE DOCTRINE OF ENLIGHTENMENT
Reading edition
According to Aśvaghosha’s Awakening of Faith, Ignorance means the sudden awakening of a thought (citta) in consciousness. This may be variously interpreted, but as long as Ignorance is conceived, not as a process requiring a certain duration of time, but an event instantaneously taking place, its disappearance which is enlightenment must also be an instantaneous happening.
