Neil Bethell Sinclair underwent a neurological transformation that he came later to understand as the full activation of the Kundalini. The overwhelming force of this activation transformed his brain and psyche into that of a poet, a mystic, and a visionary. The transformation took many years and resulted in various psychic abilities. In 1974, Sinclair began to write poetry spontaneously. During this time, his intellect became intoxicated by the continuous flow of concepts and psychic energy circulating throughout his body. The Spirit Flies Free is a collection of poems that plumb the depths of spiritual enlightenment and encompass the entirety of human experience, from politics to love, from current events to psychology.
