[233] "Bhikkhus, what kind of person is a body-witness (kāyasakkhī)? Here, bhikkhus, a certain person dwells having contacted with the body those peaceful liberations (vimokkha) that are formless, transcending forms; and, having seen with wisdom, some of his taints (āsava) are destroyed. This person, bhikkhus, is called a body-witness. Of this bhikkhu, bhikkhus, I say that there is work to be done with diligence. Why is that? [I consider:] 'Perhaps this venerable one, while resorting to suitable lodgings, associating with good friends (kalyāṇamitta), and balancing his faculties (indriya), might realize for himself with direct knowledge, in this very life, that unsurpassed consummation of the holy life (brahmacariya) for the sake of which sons of good family rightly go forth from home into homelessness, and, having entered upon it, might dwell therein.' Seeing this fruit of diligence for this bhikkhu, bhikkhus, I say that there is work to be done with diligence."
