One should restrain one’s lust and stomach by patience; one’s hands and feet by one’s eyes; one’s eyes and ears by one’s mind; and one’s mind and words by one’s acts. That Brahmana who never omitteth to perform his ablutions, who always weareth his sacred thread, who always attendeth to the study of the Vedas, who always avoideth food that is unclean, who telleth the truth and performeth acts in honour of his preceptor, never falleth off from the region of Brahma.
In plain words: Control your desires and hunger with patience, guide your hands and feet with your eyes, rule your eyes and ears with your mind, and keep your thoughts and words in check by your actions. A Brahmana (priest and scholar) who stays clean, wears his sacred thread, studies the Vedas (holy texts), avoids impure food, tells the truth, and honors his teacher will reach the heavenly world of Brahma.
