 It is a common practice for Hasidic Jews to place kvitelach on the gravesite of a Rebbe or tzadik with the belief that the soul of the deceased will pray for them in Heaven. The visitor usually sits beside the grave to write his kvitel and meditate on his request, and then tears the kvitel and throws it on top of the grave. Many graves of Jewish holy men are constructed with special apertures for the insertion of kvitelach.
