We are in a fixed state called Ein Sof (Infinity). The Creator desires to fill us boundlessly, that we will understand and feel “from the end of the world to its end.” The problem is that we are obtuse. We lack the sense with which we can perceive the whole of reality.
We have a body that is a kind of inclusive sense. Within it are five particular senses through which we sense only this world.
But there is another sense that we do not presently feel. It is called “a soul.” In it are five particular senses, too, called Keter, Hochma, Bina, Tifferet, and Malchut. When we reveal our soul, we will sense the spiritual world through it.
There is only one thing that we lack in order to reveal our souls, to feel that even now we are in the world of Ein Sof, that everything shines around us, and there are no limits— the light of Hassadim (mercy). The light of Hassadim is love, bestowal, and rising above the ego.
In Kabbalistic terms, we are currently in a sea of light of Hochma (wisdom), but we can reveal it only to the extent that we open ourselves with the light of Hassadim.
If there is any pressure from the light of Hochma, and there is no light of Hassadim on the soul’s part with which to open itself and to shine, darkness ensues.
The point in the heart within us is like a drop of “the semen of the soul.” Studying Kabbalah brings the surrounding light to it and gradually builds the light of Hassadim in it. Thus, the soul evolves and fills with the light of Hochma.
