The Vaishya and the Shudra should get over their difficulties by riches; the Brahmana should do so by Mantras and Homa. None of these, viz., a maiden, a young woman, a person unacquainted with Mantras, an ignorant person, or one who is impure, is competent to pour libations on the sacrificial fire. If any of these do so he or she is sure to go to hell, with him on whose behalf they act. Therefore none but a Brahmana well-read in the Vedas and skilled in all sacrifices should pour sacrificial libations.
