I worship Govinda, the Supreme Personality of Godhead, the cause of all causes, whose plenary portion is Maha-Visnu. All the heads of the innumerable universes [the Brahmas] live only by taking shelter of the time occupied by one of His breaths. The impersonalists do not believe in the form of the Lord, and thus they would hardly believe in the Lords sleeping. Their idea is obtained by a poor fund of knowledge; they calculate everything in terms of mans capacity. They think that the existence of the Supreme is just the opposite of active human existence; because the human being has senses, the Supreme must be without sense perception; because the human being has a form, the Supreme must be formless; and because the human being sleeps, the Supreme must not sleep. Srimad-Bhagavatam, however, does not agree with such impersonalists. It is clearly stated herein that the Supreme Lord rests in yoga-nidra, as previously discussed. And because He sleeps, naturally He must breathe, and the Brahma-samhita confirms that within His breathing period innumerable Brahmas take birth and die.
