In this simple and lively book, Samael Aun Weor describes his experiences of a wide variety of metaphysical and paranormal phenomena. In a question and answer format, he responds to the inquiries of people who have experienced events they cannot explain, like strange visitors, out of body experiences, and more. Discarding the usual pseudo-spiritual beliefs and illogical theories, Samael Aun Weor answers with lived experiences that anyone can scientifically verify for themselves. He introduces the reader to Gnosis, the practical science of awakening the consciousness, by means of which any person can experience the realities that exist beyond the physical senses.

Just as anyone can acquire practical knowledge of gravity or other physical phenomena, anyone can acquire knowledge of the physics of other dimensions. The only difference is that while physical phenomena are measured with physical senses, the paraphysical phenomena - that which occurs beyond the range of physical senses - require corresponding senses capable of perceiving them. Those senses are latent in every person; one simply needs to know how to activate them. By awakening consciousness, we acquire the means to have our own Gnosis: the experience of what is real and true. Then, one does not need to believe or disbelieve: one knows, because one has experienced the truth.
