In order to simplify this idea I would like to divide these two aspects, the meditative and the worldly, into two categories. One is connected with action, the other with repose. Much as action is needed in life, repose is just as necessary; and sometimes repose is even more necessary than action. All such complaints as nervous illnesses and disorders of the mind come from lack of repose. This realm of life which is explored by meditation is the world of repose. And as one can say that by a certain kind of work one has gathered this or that experience, or has had a certain success, or has added a particular aspect to one's knowledge, so one can also say that by this method of repose one has acquired a certain strength, illumination, and peace.
