Father, Son, and Holy Spirit. In this formula that Christians recite as though on autopilot lie the secrets for healing our world, rekindling our visionary imagination, and manifesting the Kingdom of Heaven on earth.

She looks to the ancient concept in light of the ideas of G. I. Gurdjieff and Jacob Boehme to reveal the Trinity as the "hidden driveshaft" within Christianity: the compassionate expression of the Uncreated Reality in creation.
