The Buddha said:4
"Let the bhikkhu subdue his passion for human and celestial pleasures, then, having conquered existence, he will command the Dharma. Such a one will wander rightly in the world.5
"He whose lusts have been destroyed, who is free from pride, who has overcome all the ways of passion, is subdued, perfectly happy, and of a firm mind. Such a one will wander rightly in the world.6
"Faithful is he who is possessed of knowledge, seeing the way that leads to Nirvāna; he who is not a partisan; he who is pure and virtuous, and has removed the veil from his eyes. Such a one will wander rightly in the world."7
Said the bhikkhus: "Certainly, O Bhagavat, it is so: whichever bhikkhu lives in this way, subdued and having overcome all bonds, such a one will wander rightly in the world."8
"Whatever is to be done by him who aspires to attain the tranquillity of Nirvāna let him be able and upright, conscientious and gentle, and not proud.10
"Let a man's pleasure be the Dharma, let him delight in the Dharma, let him stand fast in the Dharma, let him know how to inquire into the Dharma, let him not raise any dispute that pollutes the Dharma, and let him spend his time in pondering on the well-spoken truths of the Dharma.11
"A treasure that is laid up in a deep pit profits nothing and may easily be lost. The real treasure that is laid up through charity and piety, temperance, self-control, or deeds of merit, is hid secure and cannot pass away. It is never gained by despoiling or wronging others, and no thief can steal it. A man, when he dies, must leave the fleeting wealth of the world, but this treasure of virtuous acts he takes with him. Let the wise do good deeds; they are a treasure that can never be lost."12
And the bhikkhus praised the wisdom of the Tathāgata:13
