Always been fascinated by hand gestures, I'm entranced whenever I see people 'signing'. I wonder what the original meaning of the gesture in this old phtograph was.

It's looks to me like a benediction but the net is inconclusive.

"Shuni Mudra hand position. The tips of the middle finger and thumb touch. Emotional/spiritual use - Helps being aware of the moment, and thereby makes one more patient. Hold the finger positions with both hands, for at least a couple of minutes."

or it symbolises a rectum !
