Madhya

Lord Brahma explains in Brahma samhita(Bs 5.1) as follows:

"Krishna, who is known as Govinda, is the supreme controller. He has an eternal, blissful, spiritual body. He is the origin of all. He has no other origin, for He is the prime cause of all causes."

CC Madhya 8.136

“The transcendental body of Sri Krishna is eternal and full of bliss and knowledge. He is the son of Nanda Maharaja. He is full of all opulences and potencies as well as all spiritual mellows.

In the Sama-veda Upanishad, it is stated that Lord Sri Krishna is the divine son of Devaki. Therefore Lord Sri Krishna is the primeval Lord, and if any transcendental nomenclature is to be understood as belonging to the Absolute Personality of Godhead, it must be the name indicated by the word Krishna, which means the all-attractive. In the Padma Purana, it is also stated that out of the innumerable names of the Lord, the name of Krishna is the principal one.
