Commentary
Arjuna is giving more and more details of what he is seeing in that Cosmic Form. The items mentioned here are the symbolic insignia of Lord Vishnu.
The reference to radiance shining everywhere like blazing sun and fire does not mean tremendous amount of light in its physical sense but it indicates the glory of Pure Awareness. Consciousness is the light through which we see our own thoughts and emotions. It is the light which illumines for us various objects, sound etc. Hence Sri Krishna who Himself is Infinite Awareness is described as resplendent light immeasurable. Although the Universal Form is painted here in an objective manner it is only a subjective experience and is not an object of even intellect.
