The Kabalistic Heart

Mordecai Shia wrote in Tarot Forum:

The downward pointing triangle [and] the upward pointing triangle... form the relationship of the circulation of the "heart" in the sephiroth (the six emotions of the heart), which in turn leads to "speech". Heart here does not mean Tiferet, but rather the circulation through the paths. There are 32 paths on the tree of life, and the number 32 (lamed vet) spells out Lev which is the Hebrew word for Heart. The "six emotions" refer to six sephiroth of Chessed, Gevurah, Tiferet, Netzach, Hod, Yesod. Speech is strongly related to the energy of manifestation and malkuth, as in the kabalistic viewpoint the divine created everything through "speech". These are all concepts that relate the two triangles (and triangles themselves) as important with regards to evocation and invocation.
