The Seven Hermetic Principles, outlined in the 1912 book The Kybalion by the anonymous author known as Three Initiates, are the foundational laws of Hermetic philosophy. These principles are:
The Principle of Mentalism: "The All is Mind; the Universe is Mental."
The Principle of Correspondence: "As above, so below; as below, so above."
The Principle of Vibration: "Nothing rests; everything moves; everything vibrates."
The Principle of Polarity: "Everything is Dual; everything has poles; everything has its pair of opposites."
The Principle of Rhythm: "Everything flows, out and in; everything has its tides; all things rise and fall."
The Principle of Cause and Effect: "Every cause has its effect; every effect has its cause."
The Principle of Gender: "Gender is in everything; everything has its Masculine and Feminine Principles."
