Srimad Bhagavatam Canto 01, Chapter 06, Text 04

SB 1.6.4

prak-kalpa-visayam etam
smrtim te muni-sattama
na hy esa vyavadhat kala
esa sarva-nirakrtih
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
O great sage, time annihilates everything in due course, so how is it that this subject matter, which happened prior to this day of Brahma, is still fresh in your memory, undisturbed by time?
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
As spirit is not annihilated even after the annihilation of the material body, so also spiritual consciousness is not annihilated. Sri Narada developed this spiritual consciousness even when he had his material body in the previous kalpa. Consciousness of the material body means spiritual consciousness expressed through the medium of a material body. This consciousness is inferior, destructible and perverted. But superconsciousness of the supramind in the spiritual plane is as good as the spirit soul and is never annihilated.
