One who wants to develop the recollection of virtue should go into solitary retreat and recollect his own different kinds of virtue in their special qualities of being completely pure & untorn, as follows: Indeed, the integrity of my morality is untorn, unbroken, unspotted, unmottled, liberating, praised by the wise, detached, and productive of concentration (AN III 286). Laymen should recollect them at the level of laymen's morality, while the one gone forth into homelessness should recollect it at the degree of vinaya virtue of those gone forth.
And when a bhikkhu is devoted to this recollection of virtue, then he has respect for the training. He lives in communion with his fellows in the life of purity. He is tireless in welcoming. He is devoid of the fear of any self-reproach. He fears as evil danger even the slightest fault! He attains to fullness of faith. He has much happiness and gladness... If he penetrates no higher, he is at least headed for a happy destiny.
Now when a man is truly wise, His constant task will surely be This recollection of the Morality Blessed with such mighty potency. Vism I 222
