Srimad Bhagvata Mahapurana: Book 10: Chapter 10: Verses 39-43
Sri Suka went on : Thus glorified by them both, and (yet remaining) tethered to the mortar with a string, Lord Sri Krsna (the Ruler of Gokula) spoke laughingly to the Yaksas (as follows). The Lord said It was already known to Me how grace was showered on you both through execration by the kind-hearted sage (Narada) in the form of your utter degradation (to the state of trees), blinded as you were with the pride of fortune. From the sight of pious souls (treading the path of virtue and) possessed of equanimity (Self-Realization), who have thoroughly applied their mind to Me there follows no bondage (but emancipation) for men, any more than the obstruction of eyes from the sight of the (rays of the) sun. (On the other hand) their bondage ceases even as darkness disappears with sunshine). Therefore, 0 Nalakubara (and Manigriva), return you to your abode, now that you both have realized Me as the highest object of your adoration. Supreme devotion to Me, leading to cessation of rebirth and sought by you, has (already) been kindled (in you). Sri Suka continued : Thus spoken to (by the Lord), the two went round the Lord, who was tied to the mortar (yet), bowed low to Him again and again and, taking leave of Him, proceeded in a northerly direction.
Thus ends the tenth discourse, "Imprecation pronounced (on Nalakubara and Manigrfva) by Narada", in the first half of Book Ten of the great and glorious Bhagavata-Purana, otherwise known as the Paramahamsa-Samhita..
