Many people – either from ego or from a sense of good will or from something higher want to change the world. Help others.
So how do you do it?
By creating groups and agitation?
By having group prayers?
By group meditations?
By going to temples?
The key truth and success is something deep within you , a secret place of meditation within, a secret chakra where you go in to deep silence ( of the mind) and when you go there you can affect changes!
This is what mother said about it!
Whatever has been done in the world has been done by the very few who can stand outside the action in silence; for it is they who are the instruments of the Divine Power. They are dynamic agents, conscious instruments; they bring down the forces that change the world. Things can be done in that way, not by a restless activity. In peace, in silence and in quietness the world was built; and each time that something is to be truly built, it is in peace and silence and quietness that it must be done. It is ignorance to believe that you must run from morning to night and labour at all sorts of futile things in order to do something for the world.
Once you step back from these whirling forces into quiet regions, you see how great is the illusion! Humanity appears to you like a mass of blind creatures rushing about without knowing what they do or why they do it and only knocking and stumbling against each other. And it is this that they call action and life! It is empty agitation, not action, not true life.
I said once that, to speak usefully for ten minutes, you should remain silent for ten days. I could add that, to act usefully for one day, you should keep quiet for a year! Of course, I am not speaking of the ordinary day-to-day acts that are needed for the common external life, but of those who have or believe that they have something to do for the world. And the silence I speak of is the inner quietude that those alone have who can act without being identified with their action, merged into it and blinded and deafened by the noise and form of their own movement. Stand back from your action and rise into an outlook above these temporal motions; enter into the consciousness of Eternity. Then only you will know what true action is.
