And what’s the method in which that river can be reckoned to have two streams? By taking into account the water to the north and the south of the island, that river can be reckoned to have two streams. By the same method, the faculty of faith is the power of faith, and the power of faith is the faculty of faith. The faculty of energy is the power of energy, and the power of energy is the faculty of energy. The faculty of mindfulness is the power of mindfulness, and the power of mindfulness is the faculty of mindfulness. The faculty of immersion is the power of immersion, and the power of immersion is the faculty of immersion. The faculty of wisdom is the power of wisdom, and the power of wisdom is the faculty of wisdom. It’s because of developing and cultivating the five faculties that a mendicant realizes the undefiled freedom of heart and freedom by wisdom. And they live having realized it with their own insight in this very life due to the ending of defilements.”
