The Prashna Upanishad
Question 1:
Disciple Kabandhi : Who created the Universe?
Guru Pippalada :
The Lord meditated and brought forth Prana with Rayi
The giver of Name and Form
Male and Female
So that they would bring forth innumerable creatures!
My Notes:
Prana is the prime mover of consciousness
Consciousness interspersed with matter gives different form and name
