Hermeticism is a philosophical and spiritual tradition based on the writings attributed to Hermes Trismegistus, a legendary figure believed to be a fusion of the Greek god Hermes and the Egyptian god Thoth. This tradition emphasizes the pursuit of knowledge, the interconnectedness of all things, and the idea that understanding the universe can lead to personal transformation. Central to Hermeticism are concepts such as the Kybalion, which outlines principles like mentalism, correspondence, and vibration. Practitioners often explore alchemy, astrology, and theurgy as means to achieve spiritual enlightenment and mastery over the self and the cosmos.
