What is great faith? Great faith means that at all times you keep the mind which decided to practice, no matter what. It is like a hen sitting on her eggs. She sits on them constantly, caring for them and giving them warmth, so that they will hatch. If she becomes careless or negligent, the eggs will not hatch and become chicks. So Zen mind means always and everywhere believing in myself. I vow to become Buddha and save all people.
