Baal HaSulam, “The Essence of the Wisdom of Kabbalah”: Actual things are found even in the corporeal reality set before our eyes, although we have neither perception nor image of their essence. Such are electricity and magnetism.
Nevertheless, who can say that these names are not real when we vividly and satisfactorily know their actions? We could not be more indifferent to the fact that we have no perception of the essence of the subject itself, namely electricity itself.
In the “Introduction to The Book of Zohar” Baal HaSulam gives us the example of water, which can be cooled until it becomes solid or which can be brought to the state of vapor and cannot be seen. In other words, we cannot judge according to our perception whether something exists or not, no matter what it is. This is especially true in our times when we have discovered different frequencies, quantum phenomena, bacteria, and other phenomena that cannot be felt.
In fact we see that it is much more complicated than the picture that is depicted by our five coarse senses. I cannot limit the world to these limited senses any longer. In fact, the whole world is actually not matter but waves and energy, and I am also the same.
By studying about different phenomena, we name them according to our feelings. In the past, for example, a person looked at a mountain and said: “It is a good idea to grow olive trees on the slopes of this mountain.” Since then that mountain is called the “Mount of Olives.” Is there a spiritual attainment in that? No. But on the other hand, the idea didn’t come by chance either, but according to the order of the Lights of the vessels. There is no chance at all; the names always stem from some attainment, in this case a corporeal attainment. Kabbalists discover phenomena of the spiritual reality in their feelings and accordingly call them by names. What is more, these names are filled with a rich inner content that is stabilized in different aspects, processing, and components.
