After years of harboring vaguely Buddhist sentiments, I came across this book and found it quite fascinating. It is a somewhat disorganized assembly of very brief quotes from various discourses of the Buddha and related materials, written in modern conversational English. It encouraged me to obtain the full-length versions of the Digha Nikaya and other parts of the Pali Canon. So I credit this book for helping to get me started in a deeper exploration of the Buddha's teachings.
If you are an advanced student of Buddhism you might not be satisfied by the abbreviated material or the compiler's casual and footnote-free handling of complex, controversial matters like the "no self" issue. On the other hand, if you want to keep several copies of an affordable book handy to give to people who express an interest in learning more about Buddhism, this might be a great choice for such outreach efforts.
By the way this same material was also published in a regular-sized book entitled "The Buddha Speaks."
