Patisankhana-bala

Patisankhāna-bala: and Bhāvanā-bala: 'power of reflection', and 'power of mental development'. About these 2 powers it is said in A. II, 10:
What, o Bhikkhus, is the power of reflection? If, o Bhikkhus, someone thinks thus: 'Bad conduct in deeds, words and thoughts verily bears bad fruits both in this life, as well as in the next life', and in consequence of this consideration, he abandons bad conduct in deeds, words and thoughts, follows good conduct, and keeps his mind pure, this, o Bhikkhus, is the power of reflection.
What, o Bhikkhus, is the power of mental development? If, o Bhikkhus, a Bhikkhu develops the factors of enlightenment bojjhanga, bent on solitude, on detachment, on ceasing, and ending in deliverance, namely: awareness or mindfulness, investigating of the law, energy, rapture, tranquillity, concentration, and equanimity, this, o Bhikkhus, is the power of mental development.
