I can’t recommend this book enough, The Untethered Soul by Michael A. Singer. Singer describes the process of moving into calm awareness and quieting the mind as if it were a ‘how to’ on washing dishes. His language is simple, direct and accessible. What I especially liked is that he barely used citations and references from religious and spiritual practices. It really is his own words from his own experience. Seriously, wash the dishes, watch the mind. He makes enlightenment seem so doable! Okay, maybe a little effort.
Even if you only read the first two chapters – which are on the self-talk we do in our minds, that chattering – it is well worth it.
