Nine contemplative traditions put to a single question, the witness, the fourth, turiya, each in its own terms and none ranked above another. The book does not pretend they agree; it is built on where they genuinely diverge.

One optional thing
A revised edition is on the way. If you would like to be told when it is ready, leave your email below. It is optional, it is the only thing ever asked of you, and it will be used for nothing else.
You already have the book above. This only adds you to the revision note.
When you finish, turn to The Reader's Inquiry near the end. Put its eight questions to your own awareness, alone or with a conversational AI. Information you can read; the witness itself, you come to know.
