I have read quite a number of books about Buddhism since becoming interested in it during a holiday to Thailand three years ago and this is the most interesting and useful. For a novice to the Buddhist philosophy, this book is a "best buy".
Like other philosophies/religions that have survived over many centuries, the original teaching of the Buddha has been interpreted differently by different sects such that, like Christianity, Buddhism now has a number of different and distinct teachings. This can be very difficult to navigate for a novice, and this book's value lies in going right back to the original teachings of the Buddha himself, and concentrating on those alone. This will give people a better grounding if, at a future date, they find through their own meditation that another teaching suits them better.
Amongst the aspects that is helpfully clarified in Rahula's book is meditation, about which there seems to be many different approaches and, also, misconceptions. This was a great help to me. Also, the teaching on the "self" or, to be more precise, the absence of "self" was very revealing - I've never seen it better explained.
The book is not without without its faults however: having carefully explained the Buddha's teaching about "no-self" and the non-existence of a "soul" or any other such like entity, Rahula then realises that most novice readers (like me!) would be perplexed about how karma could then "work" through to future lives. The annoyance is, then, that as an answer to the conundrum Rahula just leaves you with a one liner from the Buddha on the conditionality of things which, frankly, has so far left me perplexed!
I guess I'd better look at his selected bibliography for further reading and meditate more!
