Also: Nonharm, Harmlessness
Ahimsa means living in a way that doesn't harm other living beings. It is the embodiment of the Golden Rule. When we practice ahimsa we respect the preferences of others as much as possible, trusting them to know what is best for them, even if they are young or elderly. We tune in to other creatures that cannot speak and so must let us know what feels good or bad through their behavior.
Although it is impossible to live (and so do good) without doing harm, we seek to minimize any suffering we may cause. In recognizing the preciousness of our own lives, we recognize that the intricate dance of life around us is also precious. Ahimsa is central virtue of the Jain religion, but is can be core to any spiritual or ethical practice.
