Bhagavad-gita As It Is Lectures

Innumerable, you cannot count. This is one of the universes, with so many planets, suns, moon. That is stated in the Vedic literature. Yasya prabhā prabhavato jagad-aṇḍa-koṭi.

Lecture on BG 2.16 -- Mexico City, February 16, 1975:

Hṛdayānanda: (translating) Are there many universes, or only one?

Prabhupāda: Innumerable, you cannot count. This is one of the universes, with so many planets, suns, moon. That is stated in the Vedic literature. Yasya prabhā prabhavato jagad-aṇḍa-koṭi (Bs. 5.40). Jagad-aṇḍa means this universe. It is ball-like, aṇḍa, egglike. Jagad-aṇḍa-koṭi. Koṭi means millions. So all combined together, that is material world. This is only one-fourth part of the creation of God. And the three-fourth part is the spiritual world.
