If we do not know how to practice in our sleep, writes Tenzin Wangyal Rinpoche, if we fall into oblivion every night, what are our chances of maintaining awareness when death comes? Take a look at your experiences in dreams - you will find out what it will be like for you in death. Look at your dream experiences and discover whether you are truly awake. This book provides detailed instructions on dream yoga, including foundational practices to do throughout the day. In the Tibetan tradition, the ability to dream lucidly is not an end in itself, but an additional area that can be mastered by performing effective higher-level practices that lead to liberation. Dream yoga is followed by sleep yoga, also called Clear Light yoga. This even higher practice is akin to the most secret Tibetan practices. Its purpose is to maintain awareness during deep sleep, when the gross conceptual mind and senses cease to function. Most people in the West cannot even imagine that such a depth of awareness is possible, but in the Tibetan spiritual traditions, Buddhist and Bon, this phenomenon is well known. The fruits of these practices are increased happiness and freedom, both in the waking state and during sleep . Tibetan Sleep and Dream Yoga provides powerful techniques for moving on the path to liberation.
