Purport: 

The material senses are engaged in gratifying the concoctions of the mind, causing many types of material desires to become prominent, one after another. One who constantly engages in the devotional service of the Lord by hearing and chanting the Lord’s transcendental glories with firm faith gets relief from the harassment of material desires. By serving the Lord one becomes strengthened in the conviction that Śrī Kṛṣṇa is the only actual enjoyer and all others are meant to share the Lord’s pleasure through devotional service. A devotee of the Lord situates Śrī Kṛṣṇa on a beautiful throne within his heart and there offers the Lord constant service. Just as the rising sun gradually eliminates all trace of darkness, the Lord’s presence within the heart causes all material desires there to weaken and eventually disappear. The words mayi hṛdi sthite (“when the heart is situated in Me”) indicate that an advanced devotee sees Lord Kṛṣṇa not only within his own heart but within the hearts of all living creatures. Thus a sincere devotee who chants and hears the glories of Śrī Kṛṣṇa should not be discouraged by the remnants of material desires within the heart. He should faithfully wait for the devotional process to naturally purify the heart of all contamination.
