Question:
I've seen pictures of thousands of letters bye the grave (ohel) of the Lubavitch Rebbi.
Is it acceptable practice to write a letter to someone who isn't alive (asking for some sort of heavenly help)?
Thank you.
Answer:
Thank you for your question.
Yes it is common practice for people to leave letters at the graves of Chasidic Rebbes and tzadikim. It is a form of making a request or a request that the soul of the tzaddik should pray n the person's behalf. Thee is also a common practice that when people come to the Western wall to place such papers indies it, as a form of praying or writing a letter to G-d with a request.
