Awareness is primordial; it is the original state, beginningless, endless, uncaused, unsupported, without parts, without change.
Consciousness is on contact, a reflection against a surface, a state of duality.
There can be no consciousness without awareness, but there can be awareness without consciousness, as in deep sleep. Awareness is absolute, consciousness is relative to its content; consciousness is always of something.
Consciousness is partial and changeful,
awareness is total, changeless, calm and silent.
And it is the common matrix of every experience.
