Baal HaSulam, “The Teaching of Kabbalah and Its Essence”: Whereas in the first discernment everyone receives equally without adding or subtracting, like Adam, in understanding the reality of this world. In viewing it, all are equal, but this is not so in understanding it—some evolve from generation to generation and some regress.
Everyone can see the same things in this world, the same phenomena. Yet, it depends on the one who sees them, whether it is a child, an adult, or an old person. The difference is in a person’s mind. After all, their senses have a mind that is behind them that analyze their perceptions; it depends on the level of one’s attainment.
It turns out that we live in very special wonderful conditions. There is no greater wonder than this world: The Creator created it and we can live in it and start our spiritual path from a state that is not spiritual. There is a reality before us that everyone can see, but everyone attains it according to his external understanding.
Suppose I took a photo of a friend working on the construction of our new building: For me it is just someone working, and only later I find out that he volunteers in brotherly mutual guarantee together with all the others, but the photo itself remains the same.
This is the uniqueness of this world: Here everything depends on how a person attains the “frames” that appear before everyone.
