In Śrīmad-Bhāgavatam there is a great deal of information given about the Vaikuṇṭha planetary systems, which are beyond the material universe. Similarly, a great deal of inconceivable information is given in the Caitanya-caritāmṛta. Any attempt to arrive at this information through experimental knowledge will fail. The knowledge simply has to be accepted. According to the Vedic method, śabda, or transcendental sound, is regarded as evidence. Sound is very important in Vedic understanding, for, if it is pure, it is accepted as authoritative. Even in the material world we accept a great deal of information sent thousands of miles by telephone or radio. In this way we also accept sound as evidence in our daily lives. Although we cannot see the informant, we accept his information as valid on the basis of sound. Sound vibration, then, is very important in the transmission of Vedic knowledge.
The Vedas inform us that beyond this cosmic manifestation there are extensive planets in the spiritual sky. This material manifestation is regarded as only a small portion of the total creation. The material manifestation includes not only this universe but innumerable others as well, but all the material universes combined constitute only one fourth of the total creation. The remaining three fourths is situated in the spiritual sky. In that sky innumerable planets float, and these are called Vaikuṇṭhalokas. In every Vaikuṇṭhaloka, Nārāyaṇa presides with His four expansions: Saṅkarṣaṇa, Pradyumna, Aniruddha and Vāsudeva. This Saṅkarṣaṇa, states Kṛṣṇadāsa Kavirāja in the eighth verse of the Caitanya-caritāmṛta, is Lord Nityānanda.
As stated before, the material universes are manifested by the Lord in the form of Mahā-Viṣṇu. Just as a husband and wife combine to beget offspring, Mahā-Viṣṇu combines with His wife māyā, or material nature. This is confirmed in the Bhagavad-gītā (BG 14.4), where Kṛṣṇa states:
- sarva-yoniṣu kaunteya mūrtayaḥ sambhavanti yāḥ
- tāsāṁ brahma mahad yonir ahaṁ bīja-pradaḥ pitā
“It should be understood that all species of life, O son of Kuntī, are made possible by birth in this material nature, and that I am the seed-giving father.” Viṣṇu impregnates māyā, the material nature, simply by glancing at her. This is the spiritual method. Materially we are limited to impregnating by only one particular part of our body, but the Supreme Lord, Kṛṣṇa or Mahā-Viṣṇu, can impregnate by any part. Simply by glancing the Lord can conceive countless living entities in the womb of material nature. The Brahma-saṁhitā confirms that the spiritual body of the Supreme Lord is so powerful that any part of His body can perform the functions of any other part. We can touch only with our hands or skin, but Kṛṣṇa can touch just by glancing. We can see only with our eyes; we cannot touch or smell with them. Kṛṣṇa, however, can smell and also eat with His eyes. When food is offered to Kṛṣṇa, we do not see Him eating, but He eats simply by glancing at the food. We cannot imagine how things work in the spiritual world, where everything is spiritual. It is not that Kṛṣṇa does not eat or that we imagine that He eats; He actually eats, but His eating is different from ours. Our eating process will be similar to His when we are completely on the spiritual platform. On that platform every part of the body can act on behalf of any other part.
