“If the doors of perception were cleansed every thing would appear to man as it is, Infinite. For man has closed himself up, till he sees all things thro’ narrow chinks of his cavern.”
Aldous Huxley’s book The Doors of Perception discusses this experience firsthand — it’s Huxley describing his experience on the psychedelic mescaline.
And it’s one of the best descriptions of the psychedelic experience.
The doors of perception are cleansed and you experience life in the Atman, the Soul.
You have an out of body experience and still you know without a doubt that you are everything.
The essence of life.
The real you.
Never born, never dies.
