Whatever I have up till now accepted as most true and assured I have gotten either from the senses or through the senses. But from time to time I have found that the senses deceive, and it is prudent never to trust completely those who have deceived us even once. — Rene Descartes, Meditations On First Philosophsy
Psychedelics made me realize this truth. This reality that is contructed by the organs of sense perception cannot be trusted in whole. Thi is is because it is not whole. It is merely part of the whole.
