A Perfect Master had a wonderful disciple whose time for the realization of God seemed to be not far off.
He had, however, one very great difficulty. He would obey his Master implicitly, but some times not exactly enough. Just a little sloppy.
One day the Master gave him an order to knock on the door of the Master's room promptly at six o'clock the next morning.
He was, however, late.
But at six o'clock exactly the milkman knocked on the door, and as the door opened it was he who received the overwhelming flood of realization.
Appointed time given by an Avatar or Master is most important and non-recurring.
