" When we approach the Upanishads for an understanding of the Cosmic Mystery, we are coming to the very heart of the Hindu experience of God. This is what we want to try to understand, not with our minds, but with our hearts: to enter into the heart and continually remind ourselves that the Upanishads are intended to lead us to the heart. The Greek fathers of the Church used to say, "Lead the thoughts from the head into the heart and keep them there." This is to open to the Cosmic Mystery. "
