[153] [63] Bhikkhus, a bhikkhu endowed with five qualities is adequate for himself and adequate for others (alaṃ attano alaṃ paresaṃ). What five? Here, bhikkhus, a bhikkhu is not indeed one of quick apprehension regarding wholesome dhammas; but he is by nature one who retains the teachings he has heard; he is one who examines the meaning of the teachings he has retained; having understood the meaning and understood the dhamma, he is one who practises in accordance with the Dhamma; and he is one of lovely speech … capable of conveying the meaning; and he is one who instructs, encourages, inspires, and gladdens his companions in the holy life. Endowed with these five qualities, bhikkhus, a bhikkhu is adequate for himself and adequate for others.
