Ever since I learned about mudras I pay closer attention to the statues I photograph. These ritual hand gestures or "seals" are used in yoga, meditation, and practices across the Asian traditions. When the fingers are held in a certain position a particular flow of energy is then connected and channeled through the mind and body.
Each of the fingers represent an energy channel:
Thumb: SPACE
Index finger: AIR
Middle finger: FIRE
Ring finger: WATER
Pinky finger: EARTH
