Master Dogen Zenji writes, in the Genjokoan, that many fully actualized Buddhas have no idea that they are Buddhas:
When buddhas are truly buddhas they do not necessarily notice that they are buddhas. However, they are actualized buddhas, who go on actualizing buddhas.
Rosanne Cash says she is not a Buddhist because she “kills ants and eats meat,” but what does she know? (Some of the most rigorous Buddhists I know eat meat from time to time.)
