The connection to the earth should be steady and joyful.
Himsa means to cause painThe translation of Patanjali Yoga Sutras by Sri Swami Satchidananda goes on to say:
Ahimsa not to cause pain
"Killing is different from causing pain. Causing pain can be more harmful than killing. Even by your words, even by your thoughts you can cause pain".Ahimsa in our lives
(Patanjali Yoga Sutras Book 11.30).
"Undisturbed calmness of mind is attained by cultivating friendliness toward the happy, compassion for the unhappy, delight in the virtuous, and indifference toward the wicked".
(The yoga sutras of Patanjali)
