Those who are sworn to sense gratification cannot understand the confidential conclusion of Vedic knowledge as explained by Me. Taking pleasure in violence, they cruelly slaughter innocent animals in sacrifice for their own sense gratification and thus worship demigods, forefathers and leaders among ghostly creatures. Such passion for violence, however, is never encouraged within the process of Vedic sacrifice.
