If you've always been curious about meditation, but didn't know where to start, I can think of no better introduction to the topic. For experienced meditators, this book can give you new ideas and inspiration for your practice.

Ram Dass tackles an immense subject with writing that is down-to-earth and wonderfully approachable, but also very thoughtful and thought-provoking. The book also contains a number of quotes from other writers on the topic - I spun out a whole secondary reading list from reading this book! 

For anyone interested in meditation at any level, I highly recommend this one!
