“One has to conquer the mind, and one may do it by following the Vedic rituals and by performing different types of sacrifice. The ultimate end of all those performances is to attain bhakti, or the devotional service of the Lord. Without bhakti one cannot understand the Supreme Personality of Godhead.” (Shrila Prabhupada, Shrimad Bhagavatam, 3.13.39 Purport)
