Patience

It is certain that an ardent aspiration for the Divine helps to progress, but patience is also needed. For it is a very big change that has to be made and, although there can be moments of great rapidity, it is never all the time like that. Old things try to stick as much as possible; the new that come have to develop and the consciousness takes time to assimilate them and make them normal to the nature.

Keep this firm faith in your mind that the thing needed is being done and will be done fully. There can be no doubt about that.
