Immortal Man, a collection of lectures from the last years of Neville's life, represents the teacher in his full maturity. Twenty-three hours with Neville take one to the outer limits of reason and into a realm of pure consciousness, where self and Self are one and creative through the dynamic of awakened imagination. This creativity, taught by Neville as by no one else - and certain of results when these are at least seen in the imagination as "natural" - proves that all the world's a stage and that, as Neville writes, You are not the mask you are wearing; you are God.
