By mere force of intention, one can imagine in an instant, a scene in America. However, can it also be experienced in actual, at that very instant? No, one cannot! There is no use imagining and framing in the fancy. It must be experienced in mind, word and body.
Similarly genuine peace cannot be obtained by merely knowing and learning about Divine Self. You may even firmly believe that joy is present in these, but that is of no avail. You must dedicate your life to win that joy and experience it and enter upon the discipline needed to acquire it. Only then do you deserve the Grace of the Lord and from that, you receive eternal love and peace.
