Temple Kehen. All of the statues at the temples have these marvelous hand gestures which I have yet to know the full meaning, but they were so compelling. While in Bali, I kept in mind a theme of hands and feet for submission at my photography club.
There is a thing called a yoga mudra which is a hand gesture that are either part of an exercise or formal spiritual practice to improve physical mental and spiritual will being! It looks very similar to this, but like you I don't know what it means either!
