The great sage Nārada thereafter thought that it was his duty to put those demigods into a condition where they could not be falsely proud of their material opulence and prestige. Nārada was compassionate and wanted to save them from their fallen life. They were in the mode of darkness, and being therefore unable to control their senses, they were addicted to sex life. It was the duty of a saintly person like Nārada to save them from their abominable condition. In animal life, the animal has no sense to understand that he is naked. But Kuvera was the treasurer of the demigods, a very responsible man, and Nalakūvara and Maṇigrīva were two of his sons. And yet they became so animalistic and irresponsible that they could not understand, due to intoxication, that they were naked. To cover the lower part of the body is a principle of human civilization, and when men or women forget this principle, they become no better than animals. Nārada therefore thought that the best punishment for them was to make them immovable living entities, or trees. Trees are, by nature’s laws, immovable. Although trees are covered by the mode of ignorance, they cannot do harm. The great sage Nārada thought it fitting that, although the brothers would be punished to become trees, by his mercy they would continue to keep their memory and be able to know why they were being punished. After changing the body, a living entity generally forgets his previous life, but in special cases, by the grace of the Lord, as with Nalakūvara and Maṇigrīva, one can remember.
Sage Nārada therefore contemplated that the two demigods should remain for one hundred years, in the time of the demigods, in the form of trees, and after that they would be fortunate enough to see the Supreme Personality of Godhead face to face, by His causeless mercy. And thus they would be again promoted to the life of the demigods and become great devotees of the Lord.
After this, the great sage Nārada returned to his abode, known as Nārāyaṇāśrama, and the two demigods turned into trees, known as twin arjuna trees. The two demigods were favored by the causeless mercy of Nārada and given a chance to grow in Nanda’s courtyard and see Lord Kṛṣṇa face to face.
Although child Kṛṣṇa was bound up to the wooden mortar, He began to proceed toward the twin trees in order to fulfill the prophecy of His great devotee Nārada. Lord Kṛṣṇa knew that Nārada was His great devotee and that the trees standing before Him as twin arjuna trees were actually the sons of Kuvera. “I must now fulfill the words of My great devotee Nārada,” He thought. Then He proceeded through the passage between the two trees. Although He was able to pass through the passage, the large wooden mortar stuck horizontally between the trees. Taking advantage of this, with great strength Lord Kṛṣṇa began to pull the rope, which was tied to the mortar. As soon as He pulled, the two trees, with all their branches and limbs, fell down immediately with a great sound. Out of the broken, fallen trees came two great personalities, shining like blazing fire. All sides became illuminated and beautiful by their presence. The two purified personalities immediately came before child Kṛṣṇa and bowed down to offer their respects and prayers in the following words.
“Dear Lord Kṛṣṇa, You are the original Personality of Godhead, master of all mystic powers. Learned brāhmaṇas know very well that this cosmic manifestation is an expansion of Your potencies, which are sometimes manifest and sometimes unmanifest. You are the original provider of the life, body and senses of all living entities. You are the eternal God, Lord Viṣṇu, who is all-pervading, the imperishable controller of everything, and You are eternal time. You are the original source of the cosmic manifestation, which is acting under the spell of the three modes of material nature—goodness, passion and ignorance. You are living as the Supersoul in all the multiforms of living entities, and You know very well what is going on within their bodies and minds. Therefore You are the supreme director of all activities of all living entities. But although You are in the midst of everything which is under the spell of the material modes of nature, You are not affected by such contaminated qualities. No one under the jurisdiction of the material modes can understand Your transcendental qualities, which existed before the creation; therefore You are called the Supreme Transcendence. Let us offer our respectful obeisances unto the lotus feet of You, Lord Vāsudeva, the Supreme Brahman, who are always glorified by Your personal internal potencies.
