In Buddhism, hand postures or mudras have symbolic meaning. The hand gesture in this painting is called the "earth witness" mudra. The Buddha summoned the earth as a witness to his enlightenment. It is a sign of determination and also represents the transformation of anger into wisdom.

Just as the Buddha awakened to his capacity, I see my own potential and want to live this new expanded vision. My future self summons and beckons me to witness my own transformation.
