1. Bhávaná Sutta. A monk may wish to be free from the ásavas and from attachment, but his wish will be fruitless unless he develops the four satipatthánas, the four sammappadhánas, the four iddhi-pádas, the five indriyas, the five powers, the seven bojjhangas, and the Eightfold Noble Path. Without these he resembles one who waits for eggs to hatch out when there is no hen. But if the monk develops these qualities he will wear away the ásavas, etc., and be aware that they are worn away, like a carpenter who knows when the handle of his adze is worn away; all these things will weaken and rot away like a ship out of the water all the winter, exposed to wind and rain. A.iv.125f.

3. Bhávaná Sutta. The cultivation of the four satipatthánas consists in contemplation of body, feelings, mind, and mind states. S.v.182.
4. Bhávaná Sutta. On psychic (iddhi ) power, its basis, its cultivation, amid the practice which leads to its cultivation. S.v.276.
