Making a small piece of art with a bunch of great meanings in it is the real beauty. Our ancestors was the god of such creations.. they made a millions of symbolic representations in which many of their real meanings are unknown for us.. they made it with their heart and soul into it.. Celtic swirl otherwise known as Triskele is one of them. Explaining about it needs a journal instead of a description. Making it short Celtic swirl symbolize the whole process of always moving forward until one reaches a state of profound enlightenment and understanding.  Also it is said the swirl represented or  connects with the concept of reincarnation. This is because the symbol consists of one seemingly continuous line that can be compared to the continuous movement of time. In this fusion where everything is concentrated to the center, I prefer mandala is the best combination for the concept of swirl.. everything to the center of energy, to the world of origin or otherwise everything from the mother energy to the outer world always bonded together with love.
