I would like to ask the great master what is the meaning of this sentence: "Take the precepts as your teacher, dwell in the four foundations of mindfulness, subdue evildoers with silence, and establish them at the beginning of all sutras."

This is when Sakyamuni Buddha was about to enter nirvana. Ananda asked the Buddha four questions. The answer Sakyamuni Buddha answered was, "Conquer evil people with silence." Ananda said at that time The question was: How to tame the evil bhikkhu. Sakyamuni Buddha replied: Put it away with silence. Silence means to respond with silence and ignore it. In the sentence "set up at the head of all sutras", Ananda was asking about the time when gathering sutras. How should the beginning of all sutras be placed? Sakyamuni Buddha replied: The four words "I have heard this" should be placed at the beginning of all sutras!
