Everything that ever happened to us, all the suffering we have gone through over the course of all of our history was for our own good. Baal HaSulam writes in Letter #23 that a person who has revealed a drop of unity with the Creator would happily chop off his arms and legs several times a day just to feel the taste of unity with the Creator at least once in his lifetime!
And that’s no exaggeration. If a person would consider how much Light one single drop of unity brings him compared to all of the most horrible suffering of this world, then he would feel that it outweighs everything!
We do not understand what the Upper Light is which clothes into the soul. We think that it’s simply something pleasant that makes us feel good. We don’t feel the true meaning of the words, “eternity, perfection, and harmony.”
