Uses Of Human Bones, Do you use them? How? Options

So on my blog I wrote down how I had ordered a human skull for a working that I'm doing, and Kinj said how he wanted someone to post a topic on the use of human bones, so, I guess that would be me. Does anyone here use human bones in their work? If so, how? I use ground up human bone in my goofer dust recipe, and I know other people try to contact the spirit of that certain bone in Necromancy. In Candomble I've seen skulls used to carry out curses. Bones are VERY potent in works that have to do with affecting the human body. Who else uses human bones, and how do you use them in your work?

In Tibetan Tantric Magick human bones are symbolic of Impermanence. Tibetan Buddhists put the bodies on hilltops (funeral) and let vultures eat their loved ones. Why? Because the physical body is deemed to be a complete illusion. To symbolize this, many tools in Tibetan Buddhism are human bones, including two pieces I have -- one, an oversized bone-handled OM MANI PADME HUM prayer wheel I use as a wand. The idea is the pratitioner must come to realize physical bones represent only the illusion of real life, that real life is in other planes of existence, and bones have no inherent power or tangible reality. However, the symbolism is powerful and the tool, although an illusion, connects with the other planes because the subconscious recognizes the nature of the universe at a true mind level.

I've never felt the human bone handle to be in any way unclean. (No Tibetan cares whether their bones are used this way after death. Since we believe we've been reborn countless times, the physical world (illusory) bones we leave behind (times thousands if you believe in rebirth) are nothing of value, because we've left behind so many skeletons. Some of the most beautiful Tibetan artifacts are made partially from human bone.
