If the mind is happy, not only the body but the whole world will be happy. So one must find out the way of becoming happy oneself. One cannot do this except by finding out about oneself by Self-enquiry. To think of reforming the world without doing that is like thinking of covering the whole world with leather to avoid the pain caused by walking on stones and thorns when the much simpler method of wearing leather shoes is available. When by holding an umbrella over your head you can avoid the sun, will it be possible to cover the face of the whole earth by tying a cloth over it to avoid the sun? If a person realises his position and stays in his own self, things that are to happen will happen. Things that are not to happen will not happen. The shakti that is in the world, is only one. All these troubles arise if we think that we are separate from that shakti.
