Well-written and inspiring guide to practising Buddhism, with practical steps to take such as meditations, prayer, actions to take or avoid, and things to think about during your day. However, because it is an introduction to more or less all of Buddha's teachings, and all the steps to enlightenment, be prepared for a challenge! The book begins with explanations of Buddhist morality, and how to meditate. Then later chapters of the book focus on Buddhist wisdom, such as the extremely complex concept of 'emptiness'. Furrowed brows are guaranteed. As another reviewer pointed out, Douglas Adams referred to this concept as 'Simultaneous tea and no tea'. I love that analogy, but I still don't understand it really!
Fortunately, the Dalai Lama does not expect us to truly understand these philosophical concepts until we have practised morality and meditation for many years, but they are included so that the book can serve as a complete overview of the Buddhist path to Enlightenment. I recommend this book if you wish to commit yourself to Tibetan Buddhism, and wish to know where you may be going, and the basic steps of how to get there.
Encouragingly, the Dalai Lama regularly assures us that this stuff is not easy, and at the end of the book, he says that we should only do that which we feel would help us, particularly if we are from different faiths. This is an example of the kindness and understanding of the author of the book.
As well as having this book as an encouraging overview and reference, I recommend books by Thich Nhat Hanh, who is a Zen Buddhist monk. Choose a title that appeals to you, as I have yet to read a book by him that is not excellent. They are beautifully and clearly written, and concentrate more on mindfulness. In this way, you can get the benefit of two schools of Buddhist thought. For further explanations of the concepts introduced in 'How to Practise', I would recommend
The Heart of the Buddha's Teaching(NB - I would personally avoid books by Kelsang Gyatso, even though they seem to have glowing reviews. Gyatso is the leader of a Buddhist sect, that some have called a cult. Also, his books just aren't very good.)
