SB 1.6 - Nārada's spiritual body
Hearing about Nārada’s birth and activities, Vyāsadeva was inquisitive to know more about the perfection of Nārada. So Vyāsa asked Nārada what he did after the sages left before the beginning of his present birth. This desire to inquire from the spiritual master is an essential factor to the progressive path, and this process is technically called sad-dharma-pṛcchā. Vyāsa wanted to know how Nārada attained his spiritual body. Since time annihilates everything in due course, how was it that Nārada was able to remember this subject matter, which happened in the previous day of Brahmā. As spirit is not annihilated even after the annihilation of the material body, so also spiritual consciousness is not destroyed. Nārada developed this spiritual consciousness even when he had his material body in the previous kalpa.
