tad vai bhagavato rupam
visuddham sattvam urjitam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
It is believed that all the universal planetary systems are situated on the extensive body of the purusa, but He has nothing to do with the created material ingredients. His body is eternally in spiritual existence par excellence.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The conception of the virat-rupa or visva-rupa of the Supreme Absolute Truth is especially meant for the neophyte who can hardly think of the transcendental form of the Personality of Godhead. To him a form means something of this material world, and therefore an opposite conception of the Absolute is necessary in the beginning to concentrate the mind on the power extension of the Lord. As stated above, the Lord extends His potency in the form of the mahat-tattva, which includes all material ingredients. The extension of power by the Lord and the Lord Himself personally are one in one sense, but at the same time the mahat-tattva is different from the Lord. Therefore the potency of the Lord and the Lord are simultaneously different and nondifferent. The conception of the virat-rupa, especially for the impersonalist, is thus nondifferent from the eternal form of the Lord. This eternal form of the Lord exists prior to the creation of the mahat-tattva, and it is stressed here that the eternal form of the Lord is par excellence spiritual or transcendental to the modes of material nature. The very same transcendental form of the Lord is manifested by His internal potency, and the formation of His multifarious manifestations of incarnations is always of the same transcendental quality, without any touch of the mahat-tattva.
