Good Vibrations (or Why Art is so Important)
The Secret of Pythagoras (DVD)
The essence of Pythagoras and his school, in my humble opinion was the understanding that numbers, letters (remember that the Hebrew alphabet's letters ARE actual numerical values), colors, Music, are all vibrate and this vibration effects our universe in more profound ways that we actually understand. This is the basis of the "secret" of Pythagoras that I have tried to convey in my video (perhaps not so successfully).
I see a strong connection of the Kabbalah, Numerology and the Tarot. The three should be studied and examined in tandem with this basic understanding kept in mind, always. When one focuses only on one facet of the Ancient Wisdom, it is akin to take a few segments of an orange and claiming to have the "whole orange expereince"...
