All that we collect and gather in the external world for our happiness and comfort is limited. Not even a thousandth part of this world that we possess can we really call our own kingdom, our world. But our mind can create and can collect numberless thoughts and impressions, which all make up its real world. All our possessions, all that we collect in life, all these things which we shall have to leave one day are transitory; but that which we have created in our thought, in our mind, that lives.
