"While I was studying at Budapest in 2005, I remember looking for books which could help me get a useful perspective on my confused experiences. There was no lack of explanation and advice, but they were missing a concrete direction: ‘Interesting ideas, but what do I do and how?’ I believe that good instruction should enable one to do more than before, shed light on the ‘what’ and ‘how’, and even on the ‘why’. The first book which gave me a tangible foothold was Ajahn Sumedho’s short book, The Four Noble Truths. It provided an introduction to a practical method of investigation with examples of Ajahn Sumedho’s own struggles. Later, when I was staying at Amaravati Buddhist Monastery in England, I read his other book Mindfulness: the Path to the Deathless and found it illuminating as well. I mention these books here because certain topics are covered in more detail there, and if you are reading this book, they might also be helpful. Here, I collect advice and teachings that I wish I had read, or someone had told me sooner, during the years since those early books. The right answer remains obscured until we learn how to ask the right question." (excerpt from the introduction)
