It is impossible to escape material bondage without devotional service in the association of devotees.
My dear Uddhava, I am personally the ultimate shelter and way of life for saintly liberated persons, and thus if one does not engage in My loving devotional service, which is made possible by associating with My devotees, then for all practical purposes, one possesses no effective means for escaping from material existence. It is generally (prāyeṇa) impossible to escape material bondage without devotional service in the association of devotees, one can simply imagine the probabilities of liberation in Kali-yuga without the Kṛṣṇa consciousness movement. The chances are certainly zero. One may concoct a type of liberation on the mental platform, or one may live in a so-called spiritual society of mutual flattery, but if one actually wants to go back home, back to Godhead, and see with spiritual eyes the beautiful kingdom of God called Kṛṣṇaloka, one must take to Lord Caitanya’s movement and worship Lord Kṛṣṇa in the association of the bhakta-gaṇa, the devotees of the Lord.
