"Reading the Vedas, making offerings to priests, or sacrifices to the gods, self-mortification by heat or cold, and many such penances performed for the sake of immortality, these do not cleanse the man who is not free from delusions.7
"Anger, drunkenness, obstinacy, bigotry, deception, envy, self-praise, disparaging others, superciliousness and evil intentions constitute uncleanness; not verily the eating of flesh.8
"A middle path, O bhikkhus, avoiding the two extremes, has been discovered by the Tathāgata—a path which opens the eyes, and, bestows understanding, which leads to peace of mind, to the higher wisdom, to full enlightenment, to Nirvāna!9
"What is that middle path, O bhikkhus, avoiding these two extremes, discovered by the Tathāgata that path which opens the eyes, and bestows understanding, which leads to peace of mind, to the higher wisdom, to full enlightenment, to Nirvāna?10
"Let me teach you, O bhikkhus, the middle path, which keeps aloof from both extremes. By suffering, the emaciated devotee produces confusion and sickly thoughts in his mind. Mortification is not conducive even to worldly knowledge; how much less to a triumph over the senses!11
"He who fills his lamp with water will not dispel the darkness, and he who tries to light a fire with rotten wood will fail. And how can any one be free from self by leading a wretched life, if he does not succeed in quenching the fires of lust, if he still hankers after either worldly or heavenly pleasures. But he in whom self has become extinct is free from lust; he will desire neither worldly nor heavenly pleasures, and the satisfaction of his natural waned will not defile him. However, let him be moderate, let him eat and drink according to the needs of the body.12
