ŚB 2.1.28

The effulgent luminary planets like the sun and the moon are situated almost in the midplace of the universe, and as such they are to be known as the chest of the original gigantic form of the Lord. And above the luminary planets, called also the heavenly places of the universal directorate demigods, are the Mahar, Janas and Tapas planetary systems, and, above all, the Satyaloka planetary system, where the chief directors of the modes of material nature reside, namely Viṣṇu, Brahmā and Śiva. This Viṣṇu is known as the Kṣīrodakaśāyī Viṣṇu, and He acts as the Supersoul in every living being. There are innumerable universes floating on the Causal Ocean, and in each of them the representation of the virāṭ form of the Lord is there along with innumerable suns, moons, heavenly demigods, Brahmās, Viṣṇus and Śivas, all of them situated in one part of the inconceivable potency of Lord Kṛṣṇa, as stated in the Bhagavad-gītā (10.42).
