SB 1.8 - Why is the unborn born?
Because the Lord’s appearance in this world is bewildering, there are different opinions about the birth of the Unborn. Some say that the unborn is born for the glorification of pious kings like Yudhiṣṭhira. The Lord wanted to establish the rule of the Pāṇḍavas for the good of the world. Others say that He appeared to please King Yadu, one of His dearest devotees. Kṛṣṇa appeared in Yadu’s family as sandalwood appeared in the Malaya hills. Trees can grow anywhere and everywhere, yet because the sandalwood trees grow mostly in Malaya hills, the name sandalwood and the Malaya hills are interrelated. The conclusion is that the lord is ever unborn like the sun, and yet He appears as the sun rises on the eastern horizon. As the sun is never the sun of the eastern horizon, so the Lord is no one’s son.
Others say that since Vasudeva and Devakī, in their previous births as Sutapā and Pṛśni, prayed for Him, Kṛṣṇa took birth as their son. Although unborn, He takes birth for their welfare and to kill the enemies of the demigods. Some say that when Brahmā prayed for the Lord to diminish the burden of the world, He appeared. Nārāyaṇa as Garbhodakaśāyī Viṣṇu entered the material universe, and from Him Brahmā was born from the lotus that grows out of Nārāyaṇa’s navel. Brahmā is called ātma-bhū because he was directly born from his father without being put into the womb of a mother. Within the halo of the universe there is a planet called Śvetadvīpa, which is the abode of Kṣīrodakaśāyī Viṣṇu. When there is trouble in the universe that cannot be solved by the administrative demigods, they approach Brahmā, and even if Brahmā cannot solve it, then he prays at the shore of the Kṣīrodaka ocean asking the Lord to incarnate. When the earth became overburdened by the misdeeds of Kaṁsa and other demons, Brahmā prayed and was advised of the descent of Kṛṣṇa as the son of Vasudeva and Devakī.
Yet others say that the Lord appeared to rejuvenate the devotional service of hearing, remembering, worshiping and so on in order that the conditioned souls suffering from material pangs might take advantage and gain liberation. The Lord appears to reestablish the way of religion. No one but the Lord can establish the path of religion. The constitutional position of a living being is to render service to the Lord. But under illusion one becomes the servant of the senses due to material desires. Thus he becomes entangled in the cycle birth and death. First there is ignorance and then desire and then action. People suffer due to actions arising from material desires which are due to ignorance. The Lord out of His causeless mercy appears and renovates the principles of devotional service comprised of hearing, chanting, remembering, serving, worshiping, praying, cooperating, becoming friends and surrendering everything unto Him.
