hrīmānhi pāpaṃ pradveṣṭi tasya śrīrabhivardhate |
śrīmānsa yāvadbhavati tāvadbhavati pūruṣaḥ || 36 ||

Through sinfulness such a person contributeth to a fusion of castes. A fusion of castes leadeth to hell and is the foremost of all sinful acts. If he is not awakened in time, he goeth, certainly, O Krishna, to hell., and, indeed, wisdom is the only thing that can awaken him, for if he obtaineth back the eye of wisdom, he is saved. When wisdom is regained, such a man turneth his attention to scriptures; and attention to scriptures aideth his virtue. Then shame becometh his best ornament. He that hath shame hath an aversion against sin, and his prosperity also increaseth; and he that hath prosperity truly becometh a man. He that is ever devoted to virtue, and hath his mind under control, and always acteth after deliberation, never inclineth towards unrighteousness and never engageth in any act that is sinful. He that is without shame and sense is neither man nor woman. He is incapable of earning religious merit, and is like a Sudra. He that hath shame gratifieth the gods, the Pitris, and even his own self, and by this he obtaineth emancipation, which indeed, is the highest aim of all righteous persons.'
