The world is full of things that are not pleasing or beautiful, but that is no reason why one should live in a constant feeling of repulsion for these things. All feelings of shrinking and disgust and fear that disturb and weaken the human mind can be overcome. A Yogi has to overcome these reactions; for almost the very first step in Yoga demands that you must keep a perfect equanimity in the presence of all beings and things and happenings. Always you must remain calm, untouched and unmoved; the strength of the Yogi lies there. An entire calmness and quietness will disarm even dangerous and ferocious animals when they confront you.
Repulsion is a movement of ignorance. It is an instinctive gesture of self-defence. But what best protects you against any danger is not an unreasoning recoil but knowledge, knowledge of the nature of the danger and a conscious application of the means that will remove or nullify it. The ignorance from which these movements rise is a general human condition, but it can be conquered; for we are not bound to the crude human nature from which the external being starts and which is all around us.
