Ahimsa

Ahiṁsā, nonviolence, means that one should not do anything which will put others into misery or confusion. Material activities that are promised by so many politicians, sociologists, philanthropists, etc., do not produce very good results because the politicians and philanthropists have no transcendental vision; they do not know what is actually beneficial for human society. Ahiṁsā means that people should be trained in such a way that the full utilization of the human body can be achieved. The human body is meant for spiritual realization, so any movement or any commissions which do not further that end commit violence on the human body. That which furthers the future spiritual happiness of the people in general is called nonviolence.
Nonviolence is generally taken to mean not killing or destroying the body, but actually nonviolence means not to put others into distress. People in general are trapped by ignorance in the material concept of life, and they perpetually suffer material pains. So unless one elevates people to spiritual knowledge, one is practicing violence. One should try his best to distribute real knowledge to the people, so that they may become enlightened and leave this material entanglement. That is nonviolence.
