"Between the planes and spheres of existence, terrestrial and super-terrestrial, there are ladders and lattices. The one who mounts sings. He is made drunk and exalted by unfolding vistas. He ascends surefootedly, thinking not of what lies below, should he slip and lose his grasp, but of what lies ahead. Everything lies ahead. The way is endless, and the farther one reaches the more the road opens up. The bogs and quagmires, the marshes and sink-holes, the pits and snares, are all in the mind. They lurk in waiting, ready to swallow one up the moment one ceases to advance. The phantasmal world is the world which has not been fully conquered over. It is the world of the past, never of the future. To move forward clinging to the past is like dragging a ball and chain. The prisoner is not the one who has committed a crime, but the one who clings to his crime and lives it over and over. We are all guilty of crime, the great crime of not living life to the full. But we are all potentially free. We can stop thinking of what we have failed to do and do whatever lies within our power. What these powers that are in us may be no one has truly dared to imagine. That they are infinite we will realize the day we admit to ourselves that imagination is everything. Imagination is the voice of daring. If there is anything God-like about God it is that. He dared to imagine everything."
—Henry Miller (from SEXUS) [not the best writing, mixed metaphors etc., nor entirely true, but still creatively inspiring]
