Ahimsa in Jainism: how far can non-harm be taken?
I grew up next door to a Jain family in Hyderabad. The grandmother wouldn't eat after sunset (to avoid harming insects attracted to light), and they avoided root vegetables, since pulling them up kills the whole plant and the many small organisms in the soil.
Jain monks take this further. Svetāmbara monks carry a whisk to gently sweep insects from their path, and many cover their mouths with a cloth. Ahiṃsā, non-harm, is the first of the five great vows.
The Jain view is that all living beings, down to one-sensed beings like plants and even earth and water bodies, have souls. Total non-harm is impossible while you're alive; the aim is to minimise it as far as possible.
As an environmental scientist, I find this both inspiring and puzzling. Can such a strict principle guide environmental ethics? Or is it only possible for renunciants?
