Buddha was Mahaveera.

Chapter 10 - The Eight Limbs Of Yoga 

Day 78 

If you are established in non violence, violence will be dropped in your very presence by other creatures. Someone may plan to attack you. But, as soon as they come near you, they will feel your vibration which is totally non violent. Then, they will stop being violent.

The contemporary of Buddha was Mahaveera. He was the promoter of the Jain religion. He emphasized ahimsa. It is said that people up to 20 kms around him would drop their violence. And, that, even thorns would not prick anybody. 

They would become soft and be flat on the ground to avoid pricking anybody. If you are established in non violence, other creatures will drop violence in your presence.
