[305] Furthermore, bhikkhus, with the fading away of rapture (pīti) … a bhikkhu enters and dwells in the third jhāna (tatiyaṃ jhānaṃ). He drenches, steeps, fills, and pervades this very body with the bliss free of rapture, so that there is no part of his whole body that is unpervaded by the bliss free of rapture. Just as, bhikkhus, in a pond of blue lotuses, or of red lotuses, or of white lotuses, some blue lotuses, red lotuses, or white lotuses are born in the water, bound up in the water, not rising above the water, nourished while submerged within it, and from their tips down to their roots are drenched, steeped, filled, and pervaded with cool water, so that there would be no part of those blue lotuses, red lotuses, or white lotuses in their entirety that is unpervaded by cool water — even so, bhikkhus, a bhikkhu drenches, steeps, fills, and pervades this very body with the bliss free of rapture, so that there is no part of his whole body that is unpervaded by the bliss free of rapture. As he dwells thus diligent … Thus too, bhikkhus, a bhikkhu develops mindfulness directed to the body (kāyagatā sati).
