"Evolutionary Triggers" for a New Consciousness. One of the most amazing books I’ve read on the subject of human spiritual evolution is “Unknown Man: Birth of a New Species” by Yatri.
It’s an improbable book that I bought back in the early 90’s offered by mainstream publisher Simon and Shuster. The book has almost a coffee table presentation feel and format to it and is full of razor-sharp insights. I’ve held onto it for years though a number of house moves and other zigs and zags.
