The Yamas are five moral codes and the first guides of the 8 Limbs of Yoga. Ahimsa is the first of the five Yamas. The word Himsa is translated as violence. The addition of an “A” changes himsa (violence) to no violence or non-violence. So the short meaning of Ahimsa is non-violence, an instruction to live in a non-violent manner.
Ahimsa may be the most important of the Yamas. This is because the other four Yamas hinge on this first guide. After all, if we practice Ahimsa the result is a smoother journey with the other Yamas. It may make us more truthful (Satya), avoid stealing (Asetya), reduce excess (Brahmacharya), and be less possessive (Aparigraha).

Today we live in a very aggressive world. Being a little forceful here or acting out a little road rage there probably would not be seen as violent. It is easy to claim that we are not violent and that we practice Ahimsa because violence is such a strong word. Laying on the horn because someone cut us off doesn’t seem as “violent” as going all Jack Nicholson on someone’s windshield in a road rage with a golf club.
The lines become more blurred when we examine the concept of Ahimsa. What our society considers a “normal reaction to stress” becomes indistinguishable from true anger, violence and aversion. Anger, rudeness, disrespect and personal attacks become commonplace. Our harmful words and actions become normalized.
When we examine the aggressive nature of our culture it is harder to parse out simple ugliness and full blown violence. The “I win and you lose” is a tenet of everything from sports to capitalism. We end up in the danger zone of harm to others, as well harm to ourselves.
Ahimsa in a larger, social context asks us to do no harm. That automatically broadens the definition to include others, ourselves, and everything in our world. Non-violence becomes less tolerant of all harm. Ahimsa asks us to consider others and ourselves before taking any action that might cause harm. Ahimsa sheds light on how we individually create an increasingly violent, aggressive world. Practicing Ahimsa helps us change it.
