Pure Consciousness is a Fourth State of Consciousness.
Criteria for a higher state consciousness:(1) Subjectively distinct from waking,
sleeping and dreaming;(2) Involve greater breadth of sense-of-
self; and (3) Be physiologically distinct.

Let’s See EEG Patterns during TM in Real Time…
• Notice how quickly brain patterns change during TM practice.
• Notice how the coherence is uniformly higher during TM practice.

Inner Awareness during Sleep…there ’s a continuum there. It's not like I go away and come back. It's a subtle thing. It's not like I'm awake waiting for the body to wake-up or whatever …… It's me there. I don't feel like I'm lost in the experience. That's what I mean by a continuum … you know its like the fizzing on top of a soda when you've poured it. It's there and becomes active so there's something to identify with. When I'm sleeping, it's like the fizzing goes down.

Conclusion
• Frontal executive circuits seem key for the experience of higher states.
• Higher states appear to be the natural extension of development that has been going on since birth.
