These "Kedusha Connection Cords" segments of 100% pure wool (each color a different kever) were wrapped around each of the kevers of our special holy people, the tzadikim. The idea to start doing this with special kever places occurred to me approximately in 5747 and was based on the long standing tradition of wrapping red wool around the Kever of Rochel Emeinu one of the great great etc. grandmothers of the Jewish People . The tradition is to walk around in a counter clock wise direction encircling the grave 7 times (sometimes more than one series but in groups of 7). Then I (Avrohom Dovid) say some Tehillim and personal prayers and afterwards remove the wool. I use the cut up segments as book marks in the Chumash (Torah- 5 Books of Moses), Tanach (Bible), Sidur (prayer book) or Tehillim (Psalms), etc. They do help to remind oneself of the person and what they stood for. G-D should please give us all the inner and outer strength to be a messenger in a real material sense of the spiritual rainbow that all these holy people constantly reveal into eternity.
Look carefully at the photos and you'll see the various Kords wrapped around the Kevers.
There is more davening, wrapping and much work to be done!
