Origin of Joseph Campbell Bliss Quote

Now, I came to this idea of bliss because in Sanskrit, which is the great spiritual language of the world, there are three terms that represent the brink, the jumping-off place to the ocean of transcendence: sat-chit-ananda. The word “Sat” means being. “Chit” means consciousness. “Ananda” means bliss or rapture. I thought, “I don’t know whether my consciousness is proper consciousness or not; I don’t know whether what I know of my being is my proper being or not; but I do know where my rapture is. So let me hang on to rapture, and that will bring me both my consciousness and my being.” I think it worked.
