Five Elements

The Ayurvedic texts teach that each Hands finger/ Legs Toes is an extension of one of the five elements. 

1. The thumb is agni (fire) -- you might have seen children sucking their thumb, this is nature's way of aiding the digestion at an age when they are unable to chew; 
2. the forefinger is vayu (air), 
3. the middle finger is akash (ether -- the tiny intercellular spaces in the human body), 
4. the ring finger is prithvi (earth) and 
5. the little finger is jal (water)
