The wisdom of Kabbalah talks about the correction of the relationship between the broken, egoistic souls and us needing to restore the connection between them and lift the souls from the ruin. Obviously, all of this is taking place inside a person, as “everyone measures the world according to his own flaws.”
But only we, being uncorrected, see the ruin. It is similar to modern physicists who claim that by looking at the universe we change the processes taking place within it. Physicists are starting to discover that we influence reality even with what we see or think.
One might think: “How can something possibly change only by looking at it?” It is a typical response, similar to when we break something and say: “I didn’t do anything, but look what happened.” Essentially this means that physics has acknowledged that “everyone measures the world according to his own flaws,” just as the wisdom of Kabbalah says that we don’t see the world as perfect because we ourselves are flawed.
To the degree of the breaking, we see only ruins around us, but to the degree that we become perfect, we see perfection. Hence, all concealments originate in us, inside the breaking which conceals the World of Infinity from us. And the wisdom of Kabbalah explains our advanced states to us: how to correct ourselves and see an increasingly perfect world.
The more you correct yourself, the more perfect the world in front of you will become.
