[128] "What do you think of this, Rāhula? What is the purpose of a mirror?" "It is for the purpose of reflection (paccavekkhaṇa), venerable sir." "Even so, Rāhula, an action (kamma) with the body should be done only after repeated reflection; an action with speech should be done only after repeated reflection; an action with the mind should be done only after repeated reflection."
