Samādhi Due to Enthusiasm

“Bhikkhus, if a bhikkhu depends on enthusiasm in order to gain samādhi, gain unification of mind, this is called samādhi due to enthusiasm. They generate enthusiasm, try, make an effort, exert the mind, and strive so that bad, unskillful qualities don’t arise. They generate enthusiasm, try, make an effort, exert the mind, and strive so that bad, unskillful qualities that have arisen are given up. They generate enthusiasm, try, make an effort, exert the mind, and strive so that skillful qualities arise. They generate enthusiasm, try, make an effort, exert the mind, and strive so that skillful qualities that have arisen remain, are not lost, but increase, mature, and are fulfilled by development. These are called active efforts. And so there is this enthusiasm, this samādhi due to enthusiasm, and these active efforts. This is called the basis of psychic power that has samādhi due to enthusiasm, and active effort.
