26 Don't indulge in careless behaviour. Don't be the friend of sensual pleasures. He who meditates attentively attains abundant joy. When a wise man has carefully rid himself of carelessness and climbed the High Castle of Wisdom, sorrowless he observes sorrowing people, like a clear-sighted man on a mountain top looking down on the people with limited vision on the ground below. It was by attention that Indra attained the highest place among the gods.
People approve of attention, while carelessness is always condemned.
30 A bhikkhu taking pleasure in being attentive, and recognising the danger of carelessness, makes progress like a forest fire, consuming all obstacles large or small in his way. A bhikkhu taking pleasure in being attentive, and recognising the danger of carelessness, is incapable of falling away. In fact he is already close to Nirvana.
