Wanted to share this additional quote from Sharon Salzburg about 'chitta' (or citta):
“In Buddhism there is one word for mind & heart: chitta. Chitta refers not just to thoughts and emotions in the narrow sense of arising from the brain, but also to the whole range of consciousness, vast & unimpeded.â€
In any kind of meditation, we are dealing with chitta. Often we think only in terms of thoughts, but we are really dealing with anything that arises - physical, emotional, mental, astral - really most of what we experience is a combination. Anything that arises in our consciousness.
