Consciousness is said to be the ground being. What does that even mean?
https://en.wikipedia.org/wiki/Universal_mind
Universal Consciousness (redirected, here, as Universal Mind) is a concept that tries to address the underlying essence of all being and becoming in the universe. It includes the being and becoming that occurred in the universe prior to the arising of the concept of “Mind,” a term that more appropriately refers to the organic, human, aspect of Universal Consciousness. It addresses inorganic being and becoming and the interactions that occur in that process without specific reference to the physical and chemical laws that try to describe those interactions. Those interactions have occurred, do occur, and continue to occur. Universal Consciousness is the source, ground, basis, that underlies those interactions and the awareness and knowledge they imply.
