261. If one thinks to do things later that should’ve been done before he will miss the chance to gain happiness. He will be remorseful later.
262. One should say only what one would do; one should not say what one will not do. Wise people do not praise those who talk but don’t act as they speak.
263. Nibbāna, taught by the Supreme Buddha, is truly the highest happiness. Suffering ceases only there. In Nibbāna there is no sorrow or defilements. True assurance is in Nibbāna.
