This is called a Sauvastika Sign. This ancient sign is infused with a variety of symbolic meanings, particularly lightning, the sun, the power to overcome evil, and universality. The arms of the Buddhist sauvastika point in the counter clockwise direction and the sign is always in an upright “+” position.

The Buddhist sauvastika is NOT related to the Nazi swastika, which can be recognised by its arms pointing clockwise and the sign being tilted in an “x” position. The Buddhist sauvastika does not carry any implication of hatred and destruction.
