Sarah's life is connected to the Mochin [another term for Spiritual Light] and the secret of Ten Sfirot that are contained within the dimension of Binah. The number 37 appears frequently here. This was Isaac's age at the time of his binding, for example, and it was because of his binding that Sarah died. The Angel of Death appeared before Sarah and told her that Abraham was about to sacrifice their son. These events convey the various levels of spiritual Light that Sarah's life revealed in this world.
The metaphysical forces embodied by Sarah are instilled within us through thoughtful meditation upon these verses.
