Such a wonderful book. For the person who has done Vipassana or haven't done Vipassana must read it. It gives you clear idea about what Vipassana actually is, what Dharma actually is. Dharma is law of nature, it is universal and it has nothing to do with Buddhism, Jainism, Christianity, Hinduism, etc. It is very scientific. This book contains 3 day series of public talks given by Mr. S.N. Goenka at Hyderabad.
