Tendai Lotus School Teachings, p 22Q: Next, is the term “Pratyekabuddha” Sanskrit or Chinese?
A: It is Sanskrit.
Q: What is it in Chinese?
A: This is translated [into Chinese] as “one who is awakened concerning conditions.” This refers to one who lives during the time of a Buddha and, by hearing an exposition on Twelvefold Conditioned Co-arising, immediately awakens to Pratyekabuddhahood.
Q: How many varieties of Pratyekabuddhas are there?
A: There are two kinds. Those who appear during the time of the Buddha have already been mentioned. If they are to appear during a time when there is no Buddha in the world, they have an immediate spontaneous awakening to Pratyekabuddhahood while contemplating the scattering of flowers or the falling of leaves.
