Behold, Arjuna, a million divine forms, with an infinite variety of color and shape. Behold the gods of the natural world, and many more wonders never revealed before. Behold the entire cosmos turning within my body, and the other things you desire to see.
But these things cannot be seen with your physical eyes; therefore I give you spiritual vision to perceive my majestic power.
-Bhagavad Gita 11:5-8
