SILA, SAMADHI, PRAJNA

IV. 4. There too, while staying at Bhanda-gâma, the Blessed One held that comprehensive religious discourse with the brethren on the nature of upright conduct, and of earnest contemplation, and of intelligence. ‘Great is the fruit, great the advantage of earnest contemplation when set round with upright conduct. Great is the fruit, great the advantage of intellect when set round with earnest contemplation. The mind set round with intelligence is freed from the great evils–that is to say, from sensuality, from individuality, from delusion, and from ignorance.’
