Patanjali on Ahimsa Ahimsapratishtayam tatsannidhau viratyagah
When a man becomes steadfast in his abtstention from harming others, then all living creatures will cease to feel enmity in his presence.
Harmlessness of a saint is not a sign of ineffectiveness or weakness. It is a positive psychological force. When a man has truely renounced violence in his own thoughts, he begins to feel a positive atmosphere around himself. Animals are sensitive to such an atmosphere. This is the essence of Patanjali's above sutra.
