Devotional service (Bhakti) dissolves the subtle body of the living entity.
As stated in Śrīmad-Bhāgavatam (3.25.33), jarayaty āśu yā kośaṁ nigīrṇam analo yathā: “Bhakti, devotional service, dissolves the subtle body of the living entity without separate endeavor, just as fire in the stomach digests all that we eat.” The subtle material body is inclined to exploit nature through sex, greed, false pride and madness. Loving service to the Lord, however, dissolves the stubborn false ego and lifts one to pure blissful consciousness, Kṛṣṇa consciousness, the sublime perfection of existence.
