The path doesn’t last for ever.

It is a blessing to travel the path for some time, but one day it will come to an end, so always be prepared to take leave of it at any moment. However enraptured you may be at certain landscapes, or scared whenever you have to make a great effort to go ahead, don’t get too used to anything. Neither to the hours of euphoria, nor to the endless days when everything seems so difficult and progress is so slow. Don’t forget that sooner or later an angel will appear and your journey will reach an end.
