Introduction
In the body of the supreme Lord, Arjuna saw the whole universe divided in different ways and at the same time united in one form. The universe is divided into many parts such as the sun, moon, earth, planets and other bodies in space. Here he sees all of them as one form.
You need to understand this description, which is so beautiful. Later we shall enter into a meditation and pray to the Parabrahma Krsna to give us all a glimpse of what Arjuna received.
Arjuna is able to see the whole and at the same time all the parts. Even the word hologram, that we now so commonly use to describe the totality of something preserved in a fragment, does no justice to Arjuna's vision.
In a hologram, one needs to make the effort to see the whole in the fragment. In this divine vision granted to Arjuna the whole existed with the part with no separation, no discontinuity. The whole was part and the part was whole.
Of all the people on the battlefield of Kuruksetra, only Arjuna had this great fortune to behold the cosmic vision of Krsna. Only he was granted the boon of divine vision to see the entire universe within Krsna. The vision that Arjuna beheld enveloped him completely. He was, in fact, part of that vision.
Arjuna and Krsna grew up together from childhood. Krsna's sister Subhadra was Arjuna's wife. They had a deep relationship as friends. In this one moment, that relationship was redefined.
