Srimad-Bhagavatam: Canto 3 - Chapter 1 - Verse 7

Sanskrit:

तद्विलोक्य वियद्व्यापि पुष्करं यदधिष्ठितम् ।अनेन लोकान् प्राग्लीनान् कल्पितास्मीत्यचिन्तयत् ॥ ७ ॥

ITRANS:

tad vilokya viyad-vyāpipuṣkaraṁ yad-adhiṣṭhitamanena lokān prāg-līnānkalpitāsmīty acintayat

Translation:

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:

The seeds of all the planets in the universe were impregnated in the lotus on which Brahmā was situated. All the planets were already generated by the Lord, and all the living entities were also born in Brahmā. The material world and the living entities were all already generated in seedling forms by the Supreme Personality of Godhead, and Brahmā was to disseminate the same seedlings all over the universe. The real creation is therefore called sarga, and, later on, the manifestation by Brahmā is called visarga.
