Consciousness

There is no independent, separate consciousness.
Consciousness arises out of conditions.
Without conditions, there is no consciousness.
Eye & visual forms = visual consciousness.
Ear & sounds = auditory consciousness.
Nose & odors = olfactory consciousness.
Tongue & tastes = gustatory consciousness.
Body & tangible objects = tactile consciousness.
Mind & ideas/thoughts = mental consciousness.

There is no Thinker behind the Thought.
Thought itself is the Thinker.
If you remove the Thought,
there is no Thinker.

Consciousness depends on matter, sensation, perception, and mental formation (samskara) and can not exist independently of them.

"I" and "Ego" are just names.
