Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
This cosmic manifestation, the material world, is also Your body. This total lump of matter is agitated by Your potent energy known as kala-sakti, and thus the three modes of material nature are manifested. You awaken from the bed of Sesa, Ananta, and from Your navel a small transcendental seed is generated. It is from this seed that the lotus flower of the gigantic universe is manifested, exactly as a banyan tree grows from a small seed.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The three different forms of Maha-Visnu — namely Karanodakasayi Visnu, Garbhodakasayi Visnu and Ksirodakasayi Visnu, who are the origin of creation and maintenance — are gradually being described. From Maha-Visnu, Garbhodakasayi Visnu is generated, and from Garbhodakasayi Visnu, Ksirodakasayi Visnu gradually expands. Thus Maha-Visnu is the original cause of Garbhodakasayi Visnu, and from Garbhodakasayi Visnu comes the lotus flower from which Lord Brahma is manifested. Thus the original cause of everything is Visnu, and consequently the cosmic manifestation is not different from Visnu. This is confirmed in Bhagavad-gita (10.8), wherein Krsna says, aham sarvasya prabhavo mattah sarvam pravartate: “I am the source of all spiritual and material worlds. Everything emanates from Me.” Garbhodakasayi Visnu is an expansion of Karanodakasayi Visnu, who is an expansion of Sankarsana. In this way, Krsna is ultimately the cause of all causes (sarva-karana-karanam). 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 Krsna 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 Krsna conscious we live not in the material world but in the spiritual world.
