The Lord says that everything is resting on Him. This should not be misunderstood. The Lord is not directly concerned with the maintenance and sustenance of this material manifestation. Sometimes we see a picture of Atlas holding the globe on his shoulders; he seems to be very tired, holding this great earthly planet. Such an image should not be entertained in connection with Kṛṣṇa’s upholding this created universe. He says that although everything is resting on Him, still He is aloof.
Bhagavad-gita As It Is – Macmillan 1972 Edition
By His Divine Grace A.C. Bhaktivedanta Swami Prabhupada
Chapter 9, Text 5
na ca mat-sthāni bhūtāni
paśya me yogam aiśvaram
bhūta-bhṛn na ca bhūta-stho
mamātmā bhūta-bhāvanaḥ
na—never; ca—also; mat-sthāni—situated in Me; bhūtāni—all creation; paśya—just see; me—My; yogam aiśvaram—inconceivable mystic power; bhūta-bhṛt—maintainer of all living entities; na—never; ca—also; bhūta-sthaḥ—in the cosmic manifestation; mama—My; ātmā—Self; bhūta-bhāvanaḥ—is the source of all manifestations.
Translation
And yet everything that is created does not rest in Me. Behold My mystic opulence! Although I am the maintainer of all living entities, and although I am everywhere, still My Self is the very source of creation.
