A Brahman asked the Buddha, “Master, is there anything you would agree to kill?”

The Buddha answered, “Yes, anger. Killing anger removes suffering and brings peace and happiness.”

 ”Breathing in, I know I am breathing in. Breathing out, I know I am breathing out." After saying these sentences, we can abbreviate them by saying "In" as we breathe in, and "Out" as we breathe out. We don't try to control our breathing. Whether our in-breath is long or short, deep or shallow, we just breathe naturally and shine the light of mindfulness on it.
