It is a great transcendental science and begins with the process of hearing and chanting the name, fame, glory, etc., of the Supreme Personality of Godhead. Revival of the dormant affection or love of Godhead does not depend on the mechanical system of hearing and chanting, but it solely and wholly depends on the causeless mercy of the Lord.
When the Lord is fully satisfied with the sincere efforts of the devotee, He may endow him with His loving transcendental service. But even with the prescribed forms of hearing and chanting, there is at once mitigation of the superfluous and unwanted miseries of material existence. Such mitigation of material affection does not wait for development of transcendental knowledge. Rather, knowledge is dependent on devotional service for ultimate realization of the Supreme Truth.
