vyaktir bhagavato nṛpa
Since Lord Kṛṣṇa descends to benefit mankind in general, why would He neglect innocent young girls who loved Him more than anyone else did? Although the Lord awards Himself to His pure devotees, He is avyaya, inexhaustible, because He is aprameya, immeasurable. He is also nirguṇa, free of material qualities, and thus those who intimately associate with Him are on the same spiritual platform. He is guṇātmā, the controller or original personality behind the modes of nature, and it is specifically for this reason that He is free of them. In other words, because the modes of nature are His energy, they cannot act upon Him.
