Among the ancient mystics, shamans, Egyptians, Tibetans and even modern investigators like Carl Jung, consciousness and the dream state have been of the utmost spiritual and psychological importance. Astral projection, lucid dreaming, out-of-body experiences and vision quests are all part of the extensive practical science of dream yoga, the sacred knowledge of consciously harnessing the power of the dream state. Any sincere practitioner who actively utilises the clues in this book can open the doors to the inner dimensions of nature and the soul and, thereby, come to know the truth of the mysteries that exist beyond the reach of our physical senses.
