I went through three phases in my awareness of our planetary predicament. I don’t know if there’s a fourth, or a fifth, but I have been through three. It’s like opening up a set of Russian dolls; each one might be the last one, but then you open it up and descend another layer. I call it the Triune Response, after the Triune (three-in-one) model of brain evolution that categorizes the human brain into three stages of development – first the reptilian complex, second the limbic system, and third the neocortex. The four levels of experience can conceptualized as mental, emotional, physical and spiritual fit these correspondingly.
