Book: Ramana Maharshi - Be As You Are
If you are not a fan of repetition, this is perhaps not for you. If you like the simplicity and economy of spiritual practice that is Self Inquiry (see also Advaita Vedanta, or non-duality) this book most certainly is for you.
David Godman has compiled a number of talks, informal question and answer's with devotees into a logical and easy to follow book.
An essential for followers of Self Inquiry, I found this book to be tough at times but ultimately the repetition paid off, I feel like my practice is stronger and more open after reading this. What a gift to the world Ramana Maharshi was.
