Tibetan knot ring silver
If you pull one side it will pull another part
The symbol in the middle of the ring is called Tibetan knot (Srivatsa or the endless knot) and is one of the eight symbols of the Tibetan Buddhism. The Tibetan knot can stand for karmic consequences: pull here, something happens over there. It is an apt symbol for the Vajrayana methods: Often when we tug at one part of a knot while trying to loosen it, another part gets tighter. You have to work with the knot to get it to come undone.
The Tibetan knot with its endless configuration evokes the cyclic nature of rebirth and also calls karmic connections to mind.
