Once [said Hazrat Inayat Khan] I put to music a verse of an inspired poet of Persia, and I sang it with great joy, for the words had a beautiful meaning. Yet at the same time I always felt that the verse had a meaning beyond the apparent one which I did not understand. I had a distinct feeling that something was sealed and hidden there.
And after fifteen years it happened, when my mind was searching for a simile for a certain revelation, that a voice came, bringing it to my mind. There was no end to my joy in opening that seal which had been closed for fifteen years!
For everything there is an appointed time, and when that time comes it is revealed. That is why, although on one hand we may be eager to attain to a certain revelation, yet on the other hand we must have patience to wait for the moment of its coming.
