पारंपरिक परिचय
The Supreme Godhead here explains the different kinds of austerity and penance. First He explains the austerities and penances practiced by the body. One should offer, or learn to offer, respect to God or to the demigods, the perfect, qualified  brāhmaṇas  and the spiritual master and superiors like father, mother or any person who is conversant with Vedic knowledge. These should be given proper respect. One should practice cleansing oneself externally and internally, and he should learn to become simple in behavior.
