We get the words psychedelic, psycho, pyschology from the greek Psyche.
“She was once a mortal princess whose astounding beauty earned the ire of Aphrodite when men turned their worship from goddess to girl. Aphrodite commanded Eros make Psykhe fall in love with the most hideous of men, but the god himself fell in love with her and carried her away to his secret palace. However Eros hid his true identity, and commanded her never to look upon his face. Psykhe was eventually tricked by her jealous sisters into gazing upon the face of god, and he abandoned her. In her despair, she searched throughout the world for her lost love, and eventually came into the service of Aphrodite. The goddess commanded her perform a series of difficult labours which culminated in a journey to the Underworld. In the end Psyckhe was reunited with Eros and the couple wed in a ceremony attended by the gods.”
