One of the planets most important system of gestures is that of Mudras, aka Hand Mudras, Mudrâs, (Sanskrit, मुद्रा, literally “seal”; 印相 inzō in Japanese, wikipedia), mudras of the Buddha, or Yoga for Your Hands.
Each mudra symbolizes and invokes a divine power or deity. Monks use them in their meditation. You can use them in sculptures, dance, or wherever you require a divine reference. Rumour even has it that this science of hand and finger postures can help you to cure bodily ailments in a wonderful manner. I guess the mass of online info speaks for itself, and I barely have anything to add, not having practised the art nor witnessed it’s usage.
