Srimad Bhagavadgita Sadhaka Sanjivani -Swami Ramsukhdas
Prasida devesa jagannivnsa:- Here the term 'Jagamnivasa, denotes the cosmic form, while 'Devesa, refers to His four-armed form. Arjuna by using the term 'Jagannivasa, means to say that His cosmic form, which is the abode of the universes, has already been seen by him, and he is still beholding it. But he prays to Him, to reveal to him His divine form (Devesa) viz., the Lord of the gods).
The cosmic form of the Lord, is divine, imperishable and eternal. In this form, there are infinite universes; and Brahma, Visnu and Siva, who create, preserve and destroy these universes, which are also infinite. Infinite universes, emanate from this form and again merge into it, yet, it remains, the same without any modification. It is so unusual that the effulgence of a thousand suns blazing forth all at once, cannot be compared with, its splendour (11/12). This form, can be seen only with divine eyes. With an eye of knowledge, one perceives existence of the Lord,Who is the origin of the universe; with an emotional eye, one sees the universe, as manifestation of the Lord, but one cannot have a vision of the cosmic form, of the Lord with human eyes. As far as human eyes, are concerned, with these one can perceive, the universe neither, as originated from the Lord, nor as His manifestation, nor His cosmic form, because eyes being evolutes of matter cannot perceive, objects, beyond it.
