With patient exposition Dr. König traces the preparatory steps that every human being has to tread in forging an earthly 'house' fitting for the spiritual to incarnate into the physical. Wonder builds on wonder as we begin to recognize the wisdom with which we human beings are fashioned, and turns into awe at how intimately we are interwoven with the evolution of our earth. Indeed, we recapitulate its earlier stages in our own unfolding from the moment of conception onwards. König succeeds in bringing vividly alive a subject normally confined to the academic laboratory. What might be thought dry or difficult here becomes exciting and challenging, and we are left with a new and deeper understanding of our significance for the future of this beautiful, fragile planet.
