The Untethered Soul, by Michael A. Singer, has much to offer. Starting with the idea of the voice in your head as a ‘roommate’, you learn to watch what your ego is doing. You may be horrified to see what goes on inside your own head. That’s the ego, and it’s not your friend.
When you can release the idea that the ego is you – something terrifying once you see how active and obnoxious egos are – you can become an untethered soul.
The book is well worth a read.
