When you are steadfast in your abstention of thoughts of harm directed toward yourself and others, all living creatures will cease to feel fear in your presence.
PatanjaliThe obstacles that distract thought are disease, apathy, doubt, carelessness, indolence, dissipation, false vision, failure to attain a firm basis in yoga, and restlessness.
PatanjaliWhere the heart is full of kindness which seeks no injury to another, either in act or thought or wish, this full love creates an atmosphere of harmony, whose benign power touches with healing all who come within its influence. Peace in the heart radiates peace to other hearts, even more surely than contention breeds contention.
