A connecting thread is woven through three seemingly separate levels of interlocking dimensions of existence into a pattern which we call The Universe ... the Macrocosmos of Outer Space ... the Microcosmos of Inner Space ... cells, molecules, atoms, subatomic particles ... and the third ... the Human Mind which can conceptualize and study the cosmoses outside and within itself ... three worlds blended into One. This series of essays represents perspectives from the author's half-century in the study of psychotherapy and spiritual exploration. He suggests that the energy we call consciousness is an inherent aspect of the Universe, the instrument through which the deepest understandings can be experienced. Since we are the vehicles through which that energy of consciousness is expressed, we ourselves, represent the greatest mystery of all.
