Jains started using the open palm as a symbol in 1975. It may have the word "ahimsa" written in it. Ahimsa means non-violence.
Jainism is an ancient religion from India. A Jain is a follower of the 24 Jinas (conquerors), who have shown the way to salvation. The 24 Jinas, the enlightened ascetics, are known as the tirthankaras.
The latest of the 24 Jinas was Vardhamana, known as Mahavira (Great Hero). He lived from 599 to 527 BC.
Jainism is a strictly non-violent religion. According to the Jains every living soul is potentially divine. Humans, animals, insects and so on are all in the cycle of reincarnation. The Jains are vegetarians.
Jains believe in karma and reincarnation, but do not believe in a creator god. They believe liberation must be achieved by individuals through their own efforts.
There are about four million Jains in India. They are among the wealthiest in India. Many hospitals, schools and businesses are run by Jains.
Jain monks are called Sadu and Jain nuns are called Sadhvi.
The monks and nuns wear white robes, with the exception of the monks of the Digambara Jains, who are naked practicing complete detachment from all things.

There are two main groups of Jains,
the Shvetambara and the Digambara.
The Jain monks and nuns follow
the Five Great Vows,
known as The Mahavratas.
