Rabbi Abadi,
Is there anything real about davening at a kever – like the Rebbe’s kever in Queens? Does the place add anything to the tefilla?
And the specific piece people do there: asking the tzaddik to intercede. Legitimate, or over the line into doresh el hameisim?
Yes, there is definitely something real about praying at the kever of a tzaddik, but I would not make it mystical.
A person can pray to Hashem almost anywhere. You can pray in shul, at home, at the beach, on a rooftop, or at the grave of a talmid chacham. The best place is the place where you are able to connect, understand what you are saying, and have the strongest kavanah.
So if going to the Rebbe’s kever inspires you, gives you humility, reminds you of the greatness of a tzaddik, and helps you speak sincerely to Hashem, then wonderful. That can certainly add something to your tefillah. On the other hand, if there are fifty people around you and all the activity makes it difficult for you to concentrate, you may actually pray better in a quiet room at home. The kever itself is not magic.
As far as asking the tzaddik to intercede for you, there is actually a very clear basis for that in Chazal. The Gemara says that Kalev went to the graves of the Avot and said:
אבותי, בקשו עלי רחמים שאנצל מעצת מרגלים
“My fathers, ask for mercy for me that I should be saved from the plan of the spies.”
(Sotah 34b)
We also find in Ta’anit 16a the concept of going to a cemetery כדי שיבקשו עלינו מתים רחמים, so that the deceased should ask for mercy on our behalf.
So asking a tzaddik, “Please pray for me,” or “Please ask Hashem to have mercy on me,” is not the prohibition of דורש אל המתים.
Doresh el hameisim is something quite different. It involves attempting to communicate with the dead in an occult way, trying to obtain information from them, summon them, receive messages from them, and similar practices. That is how the Rambam describes the prohibition (Hilchot Avodah Zarah 11).
The important distinction is that we pray to Hashem. We do not ask the tzaddik to heal us, give us money, or control what happens to us. But asking a tzaddik to pray to Hashem for us has precedent directly in the Gemara.
As for the kvittels and the various customs that have developed around places such as the Ohel, I don’t see anything wrong with them, but I also would not give them some inherent magical significance. Customs develop. Someone writes down his needs, another person does the same, and eventually it becomes the accepted thing to do. The same is true of putting notes into the Kotel.
If writing a kvittel helps you organize your thoughts, express your needs, feel humility, or connect emotionally, then go ahead. It can be a positive thing. But the piece of paper does not have any special power, and you do not need a particular ritual in order for Hashem to hear you.
So yes, pray at a kever if it helps your tefillah. Yes, you may ask the tzaddik to be melamed zechut and to ask rachamim for you. And if the kvittel and the other customs help you connect, that’s fine too.
Just don’t confuse the method with the objective. The objective is still the same: you are praying to Hashem.
Thank you rabbi for taking the time to answer so thoroughly.
