The holiest of holy places of Israel is The Jerusalem Western Wall in Jerusalem. The Western Wall is part of a vast retaining wall built by Herod around the Temple Mount; this is the most visible structure remaining from The Second Temple. It attracts thousands of Jewish worshippers daily, who come to pray and lay out their problems and seek for heavenly guidance. It is because  the Divine Presence rests on the Western Wall more than other places. (Exodus 2:2 and Song of Songs 2:4)

  One of the ancient Jewish traditions that is going back hundreds of years is to place a prayer, written on a small piece of paper, or Tzetel into a crack in the Wall. Many tears have been shed as a "Tzetel" has been put into The Western Wall. The amount and types of  requests are endless: one is asking for a speedy recovery for a sick person, another may be seeking his soul mate, yet another may be asking for G-d's guidance for a personal problem. No matter what man asks for, a feeling that one's burdens are being shared and will be alleviated, is often felt after the tzetel, with sincere prayer, is inserted into the Wall.

   Also, the Talmud teaches that all prayers ascend to heaven through Jerusalem, namely through The Western Wall. So praying or placing Tzetel into  the Wall is like having a continual prayer linked to the prime source.
