Question: The sources speak about reward. Is it correct to say that according to the effort one makes so will be the reward?
Answer: That is absolutely right. That is why it is said: “According to the sorrow, so is the reward.”
Question: I did not understand this for a long time, but today I finally understood and felt great, sincere joy from it. What happens to a person when the essence of what has been said suddenly becomes clear to him?
Answer: He simply receives a very small portion of the upper light.
Question: At the corporeal level, the concept of sorrow is associated with some kind of torment. But Kabbalah says: “Sorrow is a feeling of hunger.” That is, the more hungry a person feels, the more he will feel the pleasure from eating.
It turns out that the more spiritual hunger we have, the more pleasure we will receive from the fact that the Creator fills us with light. Is it true that I should feel not my own hunger but the hunger of my friends in the ten? If I start preparing a “meal” for them and they begin to receive fulfillment, it will be a great pleasure.
Answer: I think we should aim to feel the lack of a Kli (Vessel): what do we still lack so that we can attract the Creator, fill Him, feel our real Kli, real desire and deficiency (Hisaron).
From the Daily Kabbalah Lesson 7/25/23, “According to the Sorrow, So Is the Reward”
