A mind state represented by the concept of satchitanada" means an experience.. The reality of the experience is what it is, 'satchitanada' is merely a word to represent the real. The real is always on the other side of words, words are like signposts pointing to the real, but are not real in themselves, except of course as concepts. The real represented by the concept of 'satchitananda' is the same as that represented by 'enlightenment'.
Satcitananda is an experience. Prior to the experience, we have the words to suggest what the experience is like, and so that we may recognise it when it happens.
As I said, the concepts here are the ideas about what Brahman is and isn't.
