Is the art of not inflicting violence (himsa) on another living creature. This is the first of the five precepts of Buddhism and a major principle of Jainism.
The word is derived from the Sanskrit root hiṃs – to strike; hiṃsā is injury or harm, a-hiṃsā is the opposite of this, i.e. cause no injury, do no harm. Ahimsa is also referred to as nonviolence, and it applies to all living beings—including all animals—according to many Indian religions. [source-wikipedia]
In the above image, the hand with a wheel on the palm symbolises the Jain Vow of Ahimsa. The word in the middle is “Ahimsa”. The wheel represents the dharma chakra which stands for the resolve to halt the cycle of reincarnation through a relentless pursuit of truth and non-violence.
