The pure devotee thinks himself fallen into the ocean of birth and death and incessantly prays to the Lord to lift him up. He only aspires to become a speck of transcendental dust at the lotus feet of the Lord. The pure devotee, by the grace of the Lord, absolutely loses all attraction for material enjoyment, and to keep free from contamination he always thinks of the lotus feet of the Lord.
-Shrimad Bhagvatam Canto 2 Chapter 4 Verse 21, Translation and Purport

अविनाशि तु तद्विद्धि येन सर्वमिदं ततम् ।
विनाशमव्ययस्यास्य न कश्चित्कर्तुमर्हति ॥ १७ ॥
That which pervades the entire body you should know to be indestructible. No one is able to destroy that imperishable soul.
-BG 2.17
