The Limbs of the Body and the Space Time Hypercube
In the course of our meditation, we will also have to know how the six-seven spatial parameters correspond in Kabbalah to the limbs of the body. Chesed and gevurah, right and left, correspond to the right hand and left hand, respectively. Netzach and hod, above and below, correspond to the right leg and left leg, respectively.Tiferet and yesod, front and back, correspond to the torso and (its extension) the procreative organ, respectively.Malchut, the midpoint of space, corresponds to the mouth.
The Space–Time Hypercube
Since each of the six spatial sides of our cubic meditative sanctuary corresponds to one of the six continuous mitzvot of the Torah, the very essence of our meditation is to link the coordinate of time to the three coordinates of space, thus producing a full, four-dimensional space-time hypercube.
In Kabbalah, we are taught that the two directions of the temporal coordinate–past and future–correspond to the two primary intellectual powers of the soul, the two sefirot of chochmah ("wisdom") and binah("understanding"), whose inner lights or experiences are bitul ("selflessness") and simchah ("joy"). These two are referred to allegorically as Abba ("father") and Ima ("mother"), respectively. They give birth to the rectified emotions of the heart, the six attributes from chesed to yesod, which correspond to the six continuous commandments of the Torah.
