8.4.14

etan mahārāja taverito mayā kṛṣṇānubhāvo gajarājamokṣaṇam /
svargyaṃ yaśasyaṃ kalikalmaṣāpahaṃ duḥsvapnanāśaṃ kuruvarya śṛṇvatām //

14. O king, this glorious work of Sri Krishna (Narayana), viz., the rescue of the great elephant has been told thee by me. It is capable of leading those who listen to it to Swarga and to renown; it removes their sins brought on by Kali and prevents their bad dreams, O best of Kurus.
