I have a suggestion for closed minded individuals. Practice some of Aleister Crowley’s rituals, which has the potential to unlock or change the ways of perceiving the world or thyself. A lot of close minded individuals perceive what is based on their culture, parents, teachers, and people within their lives.
Warning: Crowley’s system of magic will fuck with your brain until the impossible becomes possible and you get out of the current reality, which becomes an infinity of anything can be possible. This will allow an individual to learn how to change their focus and look at different reality grids.
