[376] Bhikkhus, on whatever occasion, as a bhikkhu investigates, examines, and enters upon a thorough inquiry into that dhamma with wisdom (paññā), unflagging energy (vīriya) is aroused in him — on that occasion the energy factor of awakening (vīriyasambojjhaṅga) is aroused in the bhikkhu; on that occasion the bhikkhu develops the energy factor of awakening; on that occasion the energy factor of awakening in the bhikkhu comes to fulfillment by development. For one whose energy is aroused, there arises rapture (pīti) not of the flesh (nirāmisā).
