Your mind projects a structure and you identify yourself with it. It is in the nature of desire to prompt the mind to create a world for its fulfilment. Even a small desire can start a long line of action; what about a strong desire? Desire can produce a universe; its powers are miraculous. Just as a small matchstick can set a huge forest on fire, so does a desire light the fires of manifestation. The very purpose of creation is the fulfilment of desire. The desire may be noble, or ignoble, space (akash) is neutral -- one can fill it with what one likes: You must be very careful as to what you desire. And as to the people you want to help, they are in their respective worlds for the sake of their desires; there is no way of helping them except through their desires. You can only teach them to have right desires so that they may rise above them and be free from the urge to create and recreate worlds of desires, abodes of pain and pleasure.
