Srimad Bhagavatam Canto 12, Chapter 04, Text 06

SB 12.4.6

esa prakrtiko rajan
 pralayo yatra liyate
anda-kosas tu sanghato
 vighata upasadite
 
Translation: 
 
O King, upon the annihilation of the material elements, the universal egg, comprising the elemental amalgamation of creation, is confronted with destruction.
 
Purport: 
 
It is significant that Sukadeva Gosvami, the spiritual master of King Pariksit, is broadly discussing cosmic annihilation just before the death of his disciple. By attentively hearing the story of universal destruction, one can easily understand one’s personal departure from this temporary world to be an insignificant incident within the gigantic scope of the total material manifestation. By his deep and relevant discussions of the creation of God, Sukadeva Gosvami, as an ideal spiritual master, is preparing his disciple for the moment of death.
