俱舍論疏 12.81

12.81

論「言獨覺者至不調他故」，釋獨覺名有二義：一取至果時不稟至教；二已得果，復不覺於他。具此二義名為獨覺，非因位不因教也。

On the Śāstra's words, "Those called 'Solitary Enlightened' ... because they do not train others": This explains the name 'Solitary Enlightened' (pratyekabuddha) as having two meanings: first, upon attaining the fruit, they do not rely on the supreme teaching; second, having already attained the fruit, they do not awaken others. Possessing these two meanings, they are called 'Solitary Enlightened'; it is not that in the causal state they did not rely on teachings.
