Kabbalah And The Nature Of The Light

Question: There are some waves outside us that pass through our five sensory organs. They become processed by the brain, and inside us, as Baal HaSulam writes, that there is some kind of lens that scrolls this reality on a screen and I see it as particles of matter.

Is he saying that if a person looks at these waves, he sees them as particles, and if he does not observe them, then they behave as waves?

Answer: This is about the wave and particle nature of the light. A few thousand years ago, Kabbalists already knew from their attainment that these were simultaneously waves and particles. If we are dealing with the receiving light, then we quantize it, and if we are talking about general fulfillment, then we measure it in waves, in properties.
