Reason behind Jains don't eat at Night

Answer:
The most important tenet of Jainism is Non-violence which extends to not harming any living being. Consuming food at night is strictly prohibited in Jainism because the microbes that disappear when there is sunlight do not really get destroyed; they take shelter in shadowy places and after the sunset, they enter and pervade the atmosphere and get into our food too. Consuming this kind of food leads to killing of these microbes. Today, even though some might believe that this extension of non-violence was applicable before the advent of electricity, certainly these microbes are invisible to our naked eye even in bright light.
