Bhikkhu sutta: A Mendicant

“Mendicants, there are these four bases of psychic power. What four? It’s when a mendicant develops the basis of psychic power that has immersion due to enthusiasm … energy … mental development … inquiry, and active effort. These are the four bases of psychic power. By developing and cultivating these four bases of psychic power, 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.”
