A sincere devotee who engages in the service of Lord Śrī Caitanya Mahāprabhu by preaching His cult all over the world will never be affected by viṣaya-taraṅga, material influences. On the contrary, in due course of time he will return to the shelter of the lotus feet of Lord Śrī Caitanya Mahāprabhu and will thus have perpetual association with Him.
(Srimad Bhagavatam----5:1:19----purport).

For one who has taken shelter at the lotus feet of Śrī Caitanya Mahāprabhu, the highest perfection of the Māyāvādīs, kaivalya, or becoming one with the Supreme, is considered hellish, to say nothing of the karmīs' aspiration to be promoted to the heavenly planets.
(Srimad Bhagavatam----5:17:3----purport).

When Sanātana Gosvāmī submitted to the lotus feet of Śrī Caitanya Mahāprabhu, his first question was 'ke āmi', 'kene āmāya jāre tāpa-traya'. In other words, he wanted to know his constitutional position and why he was suffering from the threefold miseries of material existence. This is the process of education.
(Srimad Bhagavatam----7:6:16----purport).

People from all parts of the world must call for the devotees of Lord Śrī Caitanya Mahāprabhu, who are compared to swans swimming around the beautiful lotus feet of Śrī Caitanya Mahāprabhu or bees humming around His lotus feet in transcendental pleasure, searching for honey.
(Sri Caitanya Caritamrta----1:2:2----purport).

Those under the shelter of the lotus feet of Śrī Caitanya Mahāprabhu can understand that His mode of worship of the Supreme Lord Kṛṣṇa in separation is the real worship of the Lord.
(Sri Caitanya Caritamrta----1:4:108----purport).

Śrī Narottama dāsa Ṭhākura has sung that the best qualification for taking shelter of the lotus feet of Lord Caitanya is to be the most fallen because the Lord came specifically to deliver the fallen souls. In this age there are very few scholars. Almost everyone is a fallen meat-eater, drunkard, woman-hunter or gambler. Such persons are never considered learned scholars, even if they pose as such. Because these so-called scholars superficially see that Caitanya Mahāprabhu associates with the fallen souls, they think that He is meant for a lower class of men but that they do not need Him. Thus such scholars do not take to the Kṛṣṇa consciousness movement. To be puffed up with false learning, therefore, is a disqualification for accepting the Kṛṣṇa consciousness movement. But here is a special example, for although the poetic champion was a greatly learned scholar, the Lord also favored him because of his humble submission.
(Sri Caitanya Caritamrta----1:16:108----purport).

One should hear Śrīmad-Bhāgavatam from a person who has no connection with material activities, or, in other words, from a paramahaṁsa Vaiṣṇava, one who has achieved the highest stage of sannyāsa. This, of course, is not possible unless one takes shelter of the lotus feet of Śrī Caitanya Mahāprabhu. Śrīmad-Bhāgavatam is understandable only for one who can follow in the footsteps of Śrī Caitanya Mahāprabhu.
(Sri Caitanya Caritamrta----3:5:131----purport).

Let me surrender unto the lotus feet of Sri Kṛṣṇa Caitanya Mahāprabhu, who is the most merciful Personality of Godhead. He delivers those souls who are merged in ignorance and offers them the highest gift, love of Kṛṣṇa, and thus makes them mad for Kṛṣṇa consciousness.
(Teachings Of Lord Caitanya).

Lord Caitanya once revealed Himself to this confidential devotee, Kholāvecā Śrīdhara, and offered him any opulence he liked. But Śrīdhara informed the Lord that he did not want any material opulence. He was quite happy in his present position and wanted only to gain unflinching faith and devotion unto the lotus feet of Lord Caitanya. That is the position of pure devotees. If they can be engaged twenty-four hours each day in devotional service they do not want anything else, not even the happiness of liberation or of becoming one with the Supreme.
