One book which I've found extremely helpful, though the word use is much different, is "The Transparency of Things" by Rupert Spira..
I basically flip to any page and read two paragraphs and start to apply it in practice and I'm meditating. I am going to apply Matt's teachings as well, because if it worked so well at work it will be even better during time I set aside for meditation
Yeah, I love Rupert too. His teachings were very important to me over quite some time, but Matt is taking me to places like no one else - especially since the "Love teachings" bring a beautiful balance to the sometimes very "maskuline" Advaita teachings.
