Bhagavata Tatrparya Nirnaya – 10:11:30

The entire visible and invisible Universe, by virtue of being created by vishNu, is referred to as being part of vishNu’s form by the shAstras. It is not meant to be understood as being an absolute form of Him. His true and intrinsic form is the very personification of bliss, and has eternal and infinite attributes.
