It is therefore that the seers, the sages, try to keep their tranquility at every cost, for life in the world brings up many things every day and hour to disturb that tranquility which is the secret of insight. Every little noise or disturbance in oneself and outside can upset a person who keeps the rhythm of his whole being in the proper order. It is therefore that the sages have chosen solitude and a life away from the world. But the best way of keeping one's tranquility is to keep this rhythm under the control of one's own will. By doing this one preserves one's tranquility in the midst of life's greatest turmoil.
