The bodily beauty of Śrī Kṛṣṇa is like a wave in the ocean of eternal youth. In that great ocean is the whirlpool of the awakening of ecstatic love. The vibration of Kṛṣṇa’s flute is like a whirlwind, and the flickering minds of the gopīs are like straws and dry leaves. After they fall down in the whirlwind, they never rise again but remain eternally at the lotus feet of Kṛṣṇa.
(Sri Caitanya Caritamrta--2:21:113--purport).

If persons who are very serious about being liberated from material life hear the glories of Anantadeva from the mouth of a spiritual master in the chain of disciplic succession, and if they always meditate upon Saṅkarṣaṇa, the Lord enters the cores of their hearts, vanquishes all the dirty contamination of the material modes of nature, and cuts to pieces the hard knot within the heart, which has been tied tightly since time immemorial by the desire to dominate material nature through fruitive activities. Nārada Muni, the son of Lord Brahmā, always glorifies Anantadeva in his father's assembly. There he sings blissful verses of his own composition, accompanied by his stringed instrument (or a celestial singer) known as Tumburu.
None of these descriptions of Lord Anantadeva are imaginary. They are all transcendentally blissful and full of actual knowledge. However, unless one hears them directly from a bona fide spiritual master in the line of disciplic succession, one cannot understand them. This knowledge is delivered to Nārada by Lord Brahmā, and the great saint Nārada, along with his companion, Tumburu, distributes it all over the universe. Sometimes the Supreme Personality of Godhead is described as Uttamaśloka, one who is praised by beautiful poetry. Nārada composes various poems to glorify Lord Ananta, and therefore the word saṁślokayām āsa (praised by selected poetry) is used in this verse.
The Vaiṣṇavas in the Gauḍīya-sampradāya belong to the disciplic succession stemming from Lord Brahmā. Lord Brahmā is the spiritual master of Nārada, Nārada is the spiritual master of Vyāsadeva, and Vyāsadeva wrote the Śrīmad-Bhāgavatam as a commentary on the Vedānta-sūtra. Therefore all devotees in the Gauḍīya-sampradāya accept the activities of Lord Ananta related in the Śrīmad-Bhāgavatam as authentic, and they are thus benefited by going back home, back to Godhead. The contamination in the heart of a conditioned soul is like a huge accumulation of garbage created by the three modes of material nature, especially the modes of rajas (passion) and tamas (ignorance). This contamination becomes manifest in the form of lusty desires and greed for material possessions. As confirmed herein, unless one receives transcendental knowledge in disciplic succession, there is no question of his becoming purified of this contamination.
(Srimad Bhagavatam--5:25:8--translation and purport).

After creating the material substance, the Lord (Vāsudeva) expands Himself and enters into it. And although He is within the material modes of nature and appears to be; one of the created beings, He is always fully enlightened in His transcendental position.
The living entities are separated parts and parcels of the Lord, and the conditioned living entities, who are unfit for the spiritual kingdom, are strewn within the material world to enjoy matter to the fullest extent. As Paramātmā and eternal friend of the living entities, the Lord, by one of His plenary portions, accompanies the living entities to guide them in their material enjoyment and to become witness to all activities. While the living entities enjoy the material conditions, the Lord maintains His transcendental position without being affected by the material atmosphere. In the Vedic literatures (śruti) it is said that there are two birds in one tree.* One of them is eating the fruit of the tree, while the other is witnessing the actions. The witness is the Lord, and the fruit-eater is the living entity. The fruit-eater (living entity) has forgotten his real identity and is overwhelmed in the fruitive activities of the material conditions, but the Lord (Paramātmā) is always full in transcendental knowledge. That is the difference between the Supersoul and the conditioned soul. The conditioned soul, the living entity, is controlled by the laws of nature, while the Paramātmā, or the Supersoul, is the controller of the material energy.
(Srimad Bhagavatam--1:2:31--translation and purport).
