[1392] Ānanda, at whatever time the mind (citta) of a bhikkhu whose body is tranquil and who is happy becomes concentrated, at that time the concentration factor of awakening (samādhisambojjhaṅga) is aroused by the bhikkhu; at that time the bhikkhu develops the concentration (samādhi) factor of awakening (bojjhaṅga); at that time the concentration factor of awakening comes to fulfillment by development in the bhikkhu. He closely looks on with equanimity at the mind thus concentrated.
