i took a weeklong vacation to kentucky a couple weeks ago and i brought a book with me called "Inner and Outer Peace Through Meditation" im not entirely sure who it is by because i let my friend borrow it as soon as i was finished but it does include an introduction by the dalai lama. Reading it really opens your eyes to a lot and it really motivated me to get my priorities in check and start making real true steps to becoming a better person, i'd recommend this to anybody, it even has guidance exercises in it for help with taming the ego or reaching the next steps towards the goal of selflessness and enlightenment.
Im having the same experience right now reading a book called: Alchemy; Formulas for Self-Transformation by Saint Germain.
