“‘This process entails hearing, chanting and remembering the holy name, form, pastimes, qualities and entourage of the Lord, offering service according to the time, place and performer, worshiping the Deity, offering prayers, always considering oneself the eternal servant of Kṛṣṇa, making friends with Him and dedicating everything unto Him.
