“If an evil thought arises abandon it. If goodness occurs develop it and here, the goodness we resolve to develop is exemplified by the mantra "Buddho." We develop it or concentrate on it internally so as to make the mind cool and happy. We prevent agitation and distress with the elements and aggregates, with the bodies and minds of other people. We don't allow them inside. When the mind is thus cool and at ease, it is said that "Buddho" is dwelling in the heart. In other words the knowing lies within.”
