"A brahmana qualified to offer sacrifices is better than an ordinary brahmana, and better than such a brahmana is one who has studied all the Vedic scriptures. Among many such brahmanas, one who is a devotee of Lord Visnu is the best; and among many such Vaisnavas, one who fully engages in the service of the Lord is the best."
