Srimad Bhagavadgita Sadhaka Sanjivani -Swami Ramsukhdas
Link:- After describing the Lord's cosmic form, and its splendour, Sanjaya, in the next verse, describes that Arjuna beheld the universe, in the cosmic form of the Lord.
tatraikastham jagatkrtsnam pravibhaktamanekadha
Then Arjuna, saw unfolded in that Supreme Deity, the whole universe with its many divisions concentrated at one place. 13
- In srimadbhagavata there is an anecdote. Once Yagoda beheld the Lord's cosmic form in Krsna's small mouth. Think over it that out of infinite universes there is one universe in which there is Fndia. Fn Fndia there is Vr ja zone. In Vrajab zone there is Nandagaon. Fn Nandagaon there is Nanda's house. Fn Nanda's house the child Krsna is standing. Krsna's mother named Yagoda threateningly asked Him why He had eaten dust and ordered Him to open His mouth. When He opened His mouth, Yagoda beheld the entire world, Nandagaon, Nanda's house and also herself (drtmadbhagavata 10/8/39). Similarly Arjuna also beheld the entire universe in a part of the Lord's body.
