The language of alchemy is symbolism.
The esoteric wisdom of the universe can only be uncovered by working with it. Here we see the Veil of Isis at work. Once known as a Magician, her transformative power eclipsed that of all the other deities. The unconditional love of the Madonna then, was the goal of the Great Work in the Hermetic tradition. Geometrically, our heart could be described as a centred figurate number:
In the Anahata above, we have 37 dots in the hexagon and 73 in the hexagram. Both numbers have extraordinary properties, but as reversible primes they are really mirror images of each other. Because 37 is a centred hexagonal number AND a star number, it is the seal between worlds. In other words, because it appears in both nested sequences, it allows love to manifest simultaneously in timespace—the figure is at once a hexagon and a hexagram. Here we are reminded of a quote by Thoth:
As above, so below,
As within, so without,
As the heart, so the spirit.
The Egyptian word Ab refers to the heart. The Ab is the seat of the still, small voice within—our conscience. As we become more loving we start to give freely and generously with kindness and compassion. After healing the Ab it becomes light as a feather and is able to merge with our spirit, or Ka.
The Ka is like a dolphin—free, open and playful. It is the joy felt when our mortal heart merges with our immortal spirit. The Ka is our connection to the absolute or that which never changes. Together, the Ab and the Ka make a foundation to activate, integrate and sustain our divine purpose.
So the union of heart and spirit implies the mirrored primes of 37:73. The blue hexagon (female) and the red hexagram (male) fit together like lovers as the inverse of each other. Love blossoms then, when our hearts and spirits reflect this hyperspatial ratio.
