Visvarupa Darsana Yoga-Bhagavad Gita Chapter 11 [The Vision of the Universal Form]
Arjun Said > Shaloka: 20
Although You are one, You are spread throughout the sky and the planets and all space between. O great one, as I behold this terrible form, I see that all the planetary systems are perplexed.
Dyav-aprthivyoh (the space between heaven and earth) and loka-trayam (the three worlds) are significant words in this verse because it appears that not only Arjuna saw this universal form of the Lord, but others in other planetary systems also saw it. The vision was not a dream. All who were spiritually awake with the divine vision saw it.
