Sam2 – here is the answer to your question:
I want to remain among you. And you should come to my grave.(Chayey Moharan #197)
There is nothing I need to do for myself in this world at all. I came into the world only to bring Jewish souls closer to God. But I can only help someone who comes to me and tells me what he needs. (Chayey Moharan #307)
Rabbi Nachman chose as his resting place the old Jewish cemetery of Uman , Ukraine , where the martyrs of the 1768 Uman Massacre were buried.
Prior to his death, Rabbi Nachman urged his followers to come to his grave to pray. He also made a promise that no other Tzaddik in the whole of Jewish history had ever made. Taking as his witnesses Rabbi Aaron, Rav of the town of Breslov , and Reb Naftali, his second closest disciple after Reb Nosson, Rabbi Nachman said:
“Bear witness to my words. When my days are over and I leave this world, I will still intercede for anyone who comes to my grave, says these Ten Psalms and gives a penny to charity. No matter how great his sins, I will do everything in my power, spanning the length and breadth of creation , to save him and cleanse him.”
