Those who consider devotional service to the Supreme Lord Śrī Kṛṣṇa to be something like material emotional affairs may argue that in the revealed scriptures, sacrifice, charity, austerity, knowledge, mystic powers and similar other processes of transcendental realization are recommended. According to them, bhakti, or the devotional service of the Lord, is meant for those who cannot perform the high-grade activities. Generally it is said that the bhakti cult is meant for the śūdras, vaiśyas and the less intelligent woman class. But that is not the actual fact. The bhakti cult is the topmost of all transcendental activities, and therefore it is simultaneously sublime and easy. It is sublime for the pure devotees who are serious about getting in contact with the Supreme Lord, and it is easy for the neophytes who are just on the threshold of the house of bhakti. To achieve the contact of the Supreme Personality of Godhead, Śrī Kṛṣṇa, is a great science, and it is open for all living beings, including the śūdras, vaiśyas, women and even those lower than the lowborn śūdras, so what to speak of the high-class men like the qualified brāhmaṇas and the great self-realized kings. The other high-grade activities designated as sacrifice, charity, austerity, etc., are all corollary factors following the pure and scientific bhakti cult.
