All About Bharatiya Sanatana Dharmam otherwise known as Hinduism : Ch-3.8.1.

 8. Non violence-1.

Ahimsa or non-violence is the most important virtue.

That is the reason why Patanjali Maharshi has placed it first in Yama.

Practice of Ahimsa must be in thought, word and deed.

Practice of Ahimsa is not impotence or cowardice or weakness.

It is the highest type of heroism.

The practice demands immense patience, forbearance and endurance, infinite inner spiritual strength and gigantic will-power.

Ahimsa is a modification or expression of truth only.

Satyam and Ahimsa always go together.

He who is established in Ahimsa can move the whole world. In his presence, all hostilities vanish; lion and cow, cobra and mongoose, live together peacefully.
