Ahimsa ( A principle of non-violence )
Ahimsa means not to kill anyone. Killing generates pain; hence ahimsa can mean not to cause pain to anyone.
Yoga demands ahimsa in totality. That mean, himsa does not mean only killing or hitting anyone.
That is a limited meaning of the word or only physical aspect. To hurt someone mentally is also a himsa.
That is oral himsa. Yoga also states further that even thinking ill of someone is also a himsa, which is a mental himsa. Hence, ahimsa covers
all aspects such as physical, oral, mental.
