We look in every place for happiness. Some of us search for it in physical pleasure, some in power and some in religion. Yet it has always been within reach, for it is mind itself 'the king of all creators' which is the source of true joy, wisdom and compassion. It is this discovery that constitutes 'enlightenment', 'nirvana' or 'buddhahood'. Nowadays everything seems broken; many spiritual traditions appear to have lost their effectiveness. Yet Buddha's teaching, especially as preserved in the Tibetan tradition of Buddhism, can speak to all of us directly whether we are young or old, rich or poor, male or female. This book is designed as an introduction to this age-old yet startlingly contemporary tradition. It is written from the inside of the tradition but is aimed at a modern Western audience. It does not compromise the truth and beauty of Tibetan Buddhism but is structured so as to be accessible. It is not a do-it-yourself book. There are no secret mantras or mandalas revealed. Such things must be received in the appropriate context from one's master when one is ready. However, for those who wish to see into the heart of Tibetan Buddhism, this book offers the window.
