Reverse side of Tibetan amulet

This flat, metal object, maybe 3" by 3", was amongst the items that belonged to my Parents and my Brother and were shipped over to me in Canada after my Brother died. I had no idea what it was, until yesterday, when Flickr friends, Art and Ambre, both identified it for me - a Tibetan amulet! I'm so happy to know what this rather fascinating thing is.
