Writings of Baal HaSulam, Letter 19: A person is not ready for adhesion with the Creator all at once, but gradually, as it is written, “Goodness and mercy shall follow me.” That is why he creates yearnings, which are the beginning of adhesion, as it is written, “a righteous who suffers.” He suffers because the Creator does not desire adhesion with him. That is why the person feels yearning and sorrow without love, which is necessary for adhesion. He feels suffering which will turn into the delight of adhesion.
Question: How can we aspire to a connection with the Creator in states of suffering that He sends us?
Answer: The Creator does not send us suffering. Only goodness comes from Him, but in my egoism, I feel His kind attitude in the opposite way, meaning that I experience suffering. But this is exactly the “awakening” that is necessary for attaining the goal, for changing my egoism to bestowal. Then suffering turns into pleasure.
Nothing changes besides my attitude to the world, as it is written, “You will eat what is old.” You have changed yourself and your attitude to what happens. You have ascended above your will to enjoy, and therefore, instead of suffering you experience pleasure.
You used to aspire to imaginary sources of fulfillment, but now your aspiration for the Creator, your sorrow and suffering turn into fulfillment because you don’t want anything but this. You only want to desire Him, and this already fulfills you.
