Triquetra/Trinity Knot

In lieu of the wearing o' the green,  I'm wearing one of these today.  Actually, I've been wearing it every day since I received it as a gift from my mother who recently visited Dublin with my sister. I love this beautiful knot and  its modern Celtic Christian use to represent the Trinity (Father, Son, and Holy Ghost) and to evoke thoughts of eternal perspective.

The package this charm arrived in had a short note enclosed explaining each item and where it was purchased and for whom, I got a kick out of the note because it reminded me of the notes my grandma Molly would include with her gifts to us throughout our childhood.  I knew that my gift was a Trinity Knot charm, but I didn't know what a trinity knot is.  Well....what an odd feeling to examine this lovely little charm and realize that its pattern is one that I have found myself mindlessly tracing with my fingers or  my eyes (does anybody else do that?  find a spot on the wall or ceiling and "trace" a pattern with your eyes? Or am I the only weirdo?) since childhood.

If we are having a conversation, and you notice that I am rubbing my thumbnail with my forefinger, it is more likely than not that this is the pattern I am tracing.  If I am staring at a ceiling fan, seemingly lost in thought, it is more likely than not that I am tracing this pattern in my mind.

I find this odd.  Perhaps just a tad bit haunting.  Not haunting in a scary way, more like a "insert 'Twilight Zone' theme song here" kind of way.

I don't technically believe in reincarnation, but I have questions about some of the things in life that feel "old" to me the first time I experience them.  This is one of those things I guess.  Although I can't find in my family records the Irish connection, I am told that there is one (and I'm frankly too lazy to search through it, the programs currently available are confusing and difficult, and I have no patience for them.) and I wonder, is there a "Biological  memory" or some other unexplainable soul-source for this funny habit? I don't know, but I sure find it a strange coincidence. Whatever the source of this strange habit of mine ( o' mine?) I am very fond of this lovely little charm and the soulful connection I feel.
