The word Sefirot comes from the word “Sapir,” which means “glow” or “illumination.”
The wisdom of Kabbalah explains that there is a spiritual force of love and bestowal, which it calls “light,” and when we adapt ourselves to this force, we let it enter our desires and it shines in them. We then call the desires in which the spiritual light illuminates, “Sefirot.”
The process of spiritual attainment is one of rising above our inborn corporeal desires with a spiritual intention to love and to bestow. The more we do so, the more we reveal the Sefirot.
We discover these Sefirot in the place of what are called the spiritual worlds (Olamot), from the word for concealment (He’elem). That is, the more we rise in spiritual degrees, the more we reveal the illuminations of the Sefirot and the concealments upon our perception and senses disappear.
