Visiting the Graveside and Cemetery

I just this past week visited a graveside and placed a stone on a friend's grave marker.
This was a nice experience. He was a great friend and dare I add I say he was indeed a Tzaddik. So that was my earning last week. I happened to pick up a ritual somewhere reading about Jewish Cemetaries that I thought I'd share with you all here on the blog as I am not certain its one that many remember or know.
I read and now do myself that you can when you go to leave the cemetery grounds; pick a few pieces of grass and then toss them over your left shoulder behind you. This has psycho spiritual ramifications that are quite necessary to do in fact as a Jew and probably for all people who visit a graveyard.
To break the grass off, you have essentially removed the life force of the grass leaves and then to toss them over your shoulder, you are saying to your own soul that you are leaving the dead behind in your life. You are going on to the world of the living. I like and admire this philosophy and it does indeed make a separation of the soul from the land of the deceased to the land of the living.
One other tid bit that I think I may make into a personal ritual. I went from the cemetery to the grocery store and bought a bottle of good proof gin. It makes sense to me. We drink to be happy and forget our troubles. I bought the gin and sipped it upon returning home. I am not dead yet and I am not going to be enjoying the day that I have to indeed visit the places of rest of others. So to have a spill of gin or other spirits makes your soul lighter and that is what you need upon visiting the places of the graves of the dead.
