Bhrigu said In days of yore, the divine Brahman, for the behoof of the world, and for the protection of righteousness, laid down for modes of life. Of them, to live in the house of the preceptor is the first (in order of time). In this mode of life one should have his soul cleansed by purity of conduct, by Vedic rites and by restraints and vows and humility. He should adore the morning and evening twilights the Sun, his own consecrated hearth, and the gods. He should shake off procrastination and idleness. He should purify his soul by saluting his preceptor, by studying the Vedas, and by attending to his preceptor's instructions. He should perform his ablutions thrice.
