If a person be born in a low caste, good understanding originating from a study of the scriptures fails to rescue his body from low acts. Absolute goodness of understanding is of different degrees. It may be high, middling, and low. Even if it appears in a person of low birth, it disappears like autumnal clouds without producing any result. On the other hand, goodness of understanding which, according to its measure, has ordained the position in which the person is born, shows itself in his deeds.
शरीरमिह सत्त्वेन न तस्य परिकृष्यते। ज्येष्ठमध्यावरं सत्त्वं तुल्यसत्त्वं प्रमोदते॥
