etad rupam bhagavato

Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The conception of the virat universal form of the Lord, as appearing in the material world, is imaginary. It is to enable the less intelligent [and neophytes] to adjust to the idea of the Lord’s having form. But factually the Lord has no material form.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The conception of the Lord known as the visva-rupa or the virat-rupa is particularly not mentioned along with the various incarnations of the Lord because all the incarnations of the Lord mentioned above are transcendental and there is not a tinge of materialism in their bodies. There is no difference between the body and self as there is in the conditioned soul. The virat-rupa is conceived for those who are just neophyte worshipers. For them the material virat-rupa is presented, and it will be explained in the Second Canto. In the virat-rupa the material manifestations of different planets have been conceived as His legs, hands, etc. Actually all such descriptions are for the neophytes. The neophytes cannot conceive of anything beyond matter. The material conception of the Lord is not counted in the list of His factual forms. As Paramatma, or Supersoul, the Lord is within each and every material form, even within the atoms, but the outward material form is but an imagination, both for the Lord and for the living being. The present forms of the conditioned souls are also not factual. The conclusion is that the material conception of the body of the Lord as virat is imaginary. Both the Lord and the living beings are living spirits and have original spiritual bodies.
