At the core of Jainism is a doctrine which prohibits killing, violence or injury to any living thing. Certain Jain monks and nuns demonstrate this reverence for all life by wearing cloth masks over their faces to prevent them from accidentally inhaling tiny flying insects and sweeping the ground in front of them to avoid crushing any living organism under their feet.
Tranquility is the prevailing sentiment in Jain art and iconography.
An image of a Jina does not represent a god but is instead a reminder of an ideal. A diamond-shaped emblem called a srivatsa is seen on the chest of all Jina figures.
