Interesting!

Thanks, Marcia for the post.

Self-investigation (Sanskrit term: Atma-Vichara), is a very strong and common process in Advaita school of philosophy. Ramana Maharshi, Ashtavakara, Adi Shankara, etc are done very similar investigations like this.

You are investigating the core of awareness.

• If the body sleeps, does the mind also sleep?
• Who thinks about that thought? (Mind thinks about mind!)
• Who is the witness, and who is the thinker?
• Is the witness, singular or pervasive?

These books are very much useful for your investigation: (Classic Bibles of Advaita (Non-Duality):

1. Who am I - Ramana
2. Ashtavakara Gita - Ashtavakara
3. Vivekachudamani - by Adi Shankara

They are transcendentalists and reach the bliss state by a simple investigation into themselves. These methods do not involve any kundalini yoga (some even say it is not needed or spoke against it as being basic to their methods)
