The Upanishads

Ahimsa - Non-Violence

Causing no harm to any living being.

Ahimsa is refraining from causing injury to any creature in thought, word, or deed. Recognizing the Self in all beings, how can one harm another?

One who sees all beings in the Self does not hate anyone.

Isha Upanishad, Isha Upanishad 6

Ahimsa naturally arises from seeing unity in diversity.
