Comment: We conducted a workshop on the topic “Why do prayers fail?” But if my prayer is for my friends to reveal the Creator, I won’t know if they have revealed Him or not.

My Response: You’ll be the first to know about it. That is what it says in Rabash’s article: “The one who prays for his friend is the first to receive.”

You should know the first twenty articles of Rabash by heart! There are also other articles.

Question: I know that. The question is something else. You said I should forcibly think about the good of the friends, imagine the most ideal state, and ask the Creator for it for my friends. If I pray for the Creator to unite all my friends constantly and return to this thought many times during the day, what is wrong with my prayer?

Answer: Who said it is wrong?

Comment: If it is not answered, it is incorrect.

My Response: That is what is wrong, you are waiting for an answer to it. So you are working for a reward.

If you repeat the same prayer all the time and clarify what else you can add or remove from it so it comes as much as possible from the depths of your heart, this is your reward.

Question: So the reward is that the Creator gives me the opportunity to ask and constantly returning to this request during the day?

Answer: That is why it is said: “Schar HaMitzvah–Mitzvah“—”The reward for good deed is a good deed.”
