>>11753013based. duality really is the key, and from there you can go to numerology- odd numbers being active, and even numbers being receptive. it's the solar/masculine and lunar/feminine archetypes.
but lately i've been taking the advaita vedanta pill- all duality is illusory, unity is the truth
the tarot is what really opened my mind to numerology, and the Major Arcana are a great aid to meditation. it's not just a tool for divination, it's an initiatory process that you participate in
