Inner Engineering: A Yogi's Guide to Joy

Inner Engineering by Sadhguru. For me it was an unexpectedly transformational when I read it 6 months ago. Unlike the stoicism books that teach you to condition yourself to be unaffected by external events, this is a method for taking charge of what goes on inside the body and (in my case) in the mind and emotions. As an aside, if you haven’t tried audiobooks, I would recommend trying. I find that after a while day of staring at the screen I really don’t want to stare at anything else, so my book consumption dropped considerably. With audiobooks I was able to restore it somewhat (and it’s great for filling in lost time during driving).
