SB 4.24.59 purport… The bhakti-yoga process must be carried out by avoiding the ten offenses one can commit while chanting the mahā-mantra and the sixty-four offenses one can commit while worshiping the Deity. When a devotee strictly follows the rules and regulations, Bhaktidevī becomes very much satisfied with him, and at that time he is never disturbed by anything external. A devotee is also called a muni. The word muni means “thoughtful.” A devotee is as thoughtful as a nondevotee is speculative. The nondevotee’s speculation is impure, but a devotee’s thoughts are pure. Lord Kapila and Śukadeva Gosvāmī are also called muni, and Vyāsadeva is addressed as Mahāmuni. A devotee is addressed as muni, or thoughtful, when he purely understands the Supreme Personality of Godhead. The conclusion is that when one’s heart is purified by the association of devotees and by the avoidance of the offenses committed when chanting and worshiping the Lord, the transcendental name, form and activities of the Lord are revealed by the Lord.
