Besides that other suttas better explain?
On an occasion, bhikkhus, when the mind becomes sluggish, it is timely to develop the enlightenment factor of discrimination of states, the enlightenment factor of energy, and the enlightenment factor of rapture. For what reason? Because the mind is sluggish, bhikkhus, and it is easy to arouse it with those things.
