Comment: According to the laws of physics, there are active particles of light, photons, that convey electromagnetic effects and bind the atoms and the molecules of which man is composed. In fact, the light (the photons) make us whole. If it weren’t for the light, our bodies would disintegrate into atoms.
According to the wisdom of Kabbalah, the Light also sustains the whole system.
My Response: Nothing would exist without the Light. The general Light is the Creator.
It is the same in physics. If the initial Light had not appeared, everything else could not have developed: waves, matter, etc.
From a Kabbalistic perspective, the Light ties our desires together. The Light gradually disappears and seems to fade away to the extent that our desires begin to gradually retreat, and so everything begins to fall apart.
This is the reason that we see that everything is divided into different parts in our world, although it is all one common whole.
