Once upon a time, Lord Kṛṣṇa, the Supreme Personality of Godhead, the bestower of all knowledge upon all living entities, from Brahmā to the insignificant ant, was sitting in the bedroom of Rukmiṇī, who was engaged in the service of the Lord along with her assistant maidservants. Kṛṣṇa was sitting on the bedstead of Rukmiṇī, and the maidservants were fanning Him with cāmaras (yak-tail fly-whisks).
Lord Kṛṣṇa's dealings with Rukmiṇī as a perfect husband are a perfect manifestation of the supreme perfection of the Personality of Godhead. There are many philosophers who propound a concept of the Absolute Truth in which God cannot do this or that. They deny the incarnation of God, or the Supreme Absolute Truth in human form. But actually the fact is different: God cannot be subject to our imperfect sensual activities. He is the all-powerful, omnipresent Personality of Godhead, and by His supreme will He can not only create, maintain and annihilate the whole cosmic manifestation but also descend as an ordinary human being to execute the highest mission. As stated in the Bhagavad-gītā, whenever there are discrepancies in the discharge of human occupational duties, He descends. He is not forced to appear by any external agency, but He descends by His own internal potency in order to reestablish the standard functions of human activities and simultaneously annihilate the disturbing elements in the progressive march of human civilization. In accordance with this principle of the transcendental pastimes of the Supreme Personality of Godhead, He descended in His eternal form as Śrī Kṛṣṇa in the dynasty of the Yadus.
