It's a small round object similar to a small stone. The one i got is a little pinkish in colour. It's contained in a pendent with a white buddhist figurine(not sure it's the figurine of Buddha or of the monk)
I got it from a man which claims it comes from a Buddhist monk in Thailand, he said that it gives protection and that I should wear it. He gave it cause he said that it was fate for me to had meet him. However, I'm.not sure what it is and wondering can anyone tell me what this Tian Shi Li is?
I think you can find better answers in this forum: http://cultivation.sgforums.com/forums/1169
And I think you should take a picture, it's clearer.
