tad vilokya viyad-vyapi
anena lokan prag-linan
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Thereafter he saw that the lotus on which he was situated was spread throughout the universe, and he contemplated how to create all the planets, which were previously merged in that very same lotus.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The seeds of all the planets in the universe were impregnated in the lotus on which Brahma was situated. All the planets were already generated by the Lord, and all the living entities were also born in Brahma. The material world and the living entities were all already generated in seedling forms by the Supreme Personality of Godhead, and Brahma was to disseminate the same seedlings all over the universe. The real creation is therefore called sarga, and, later on, the manifestation by Brahma is called visarga.
