pasyascaryani bharata

"O best of the Bharatas, see here the different manifestations of Adityas, Vasus, Rudras, Asvini-kumaras and all the other demigods. Behold the many wonderful things which no one has ever seen or heard of before."

"Look at My wonderful image", says Sri Krishna. Pasya = look. The Lord is yet to exhibit His Viswaroopam. He is going to enable Arjuna to see His wonderful image. He tells Arjuna to look various gods in His Viswaroopam. Alwar also says that lord Shiva, lord Brahma, Indra and all others, are all displayed in the Body of the Lord. Look at adityan = [Twelve] Adityas, vasun = [Eight] Vasu [வஸு], rudran = [eleven] Rudras, asvinau = Twins Asvini, marutas = [Forty Nine] Maruts, tata = and, bahuni = many, many, purvani = before, adrsta = never viewed ot sighted. This type of Image, Arjuna would have never seen earlier. That is, in the same image to see Adityas, Rudras, etc., simultaneously. In fact Arjuna had never heard of such an image. This image can not be seen directly, just as we see materials in this World [pratyaksham ப்ரத்யக்ஷம் ]; nor, we can deduce by logic [anumanam அனுமானம்]. Aascaryani = most wonderful. This image can not be imagined by the mind nor percievable by the sense organs. Can it be termed false, then? But such an image is proclaimed in Vedas. Sages have seen that image. Just because we do not see or can not imagine. how can we say it, as false? Thus Arjuna is going to be blessed with a never-before image of the Lord.
