The three different forms of Mahā-Viṣṇu — namely Kāraṇodakaśāyī Viṣṇu, Garbhodakaśāyī Viṣṇu and Kṣīrodakaśāyī Viṣṇu, who are the origin of creation and maintenance — are gradually being described. From Mahā-Viṣṇu, Garbhodakaśāyī Viṣṇu is generated, and from Garbhodakaśāyī Viṣṇu, Kṣīrodakaśāyī Viṣṇu gradually expands. Thus Mahā-Viṣṇu is the original cause of Garbhodakaśāyī Viṣṇu, and from Garbhodakaśāyī Viṣṇu comes the lotus flower from which Lord Brahmā is manifested. Thus the original cause of everything is Viṣṇu, and consequently the cosmic manifestation is not different from Viṣṇu. This is confirmed in Bhagavad-gītā (10.8) , wherein Kṛṣṇa says, ahaṁ sarvasya prabhavo mattaḥ sarvaṁ pravartate: “I am the source of all spiritual and material worlds. Everything emanates from Me.” Garbhodakaśāyī Viṣṇu is an expansion of Kāraṇodakaśāyī Viṣṇu, who is an expansion of Saṅkarṣaṇa. In this way, Kṛṣṇa is ultimately the cause of all causes ( sarva-kāraṇa-kāraṇam ). The conclusion is that both the material world and spiritual world are considered to be the body of the Supreme Lord. We can understand that the material body is caused by the spiritual body and is therefore an expansion of the spiritual body. Thus when one takes up spiritual activities, one’s entire material body is spiritualized. Similarly, in this material world, when the Kṛṣṇa consciousness movement expands, the entire material world becomes spiritualized. As long as we do not realize this, we live in the material world, but when we are fully Kṛṣṇa conscious we live not in the material world but in the spiritual world.
