The game of the master

Mr. Gurdjieff said that one of the roles of the teacher is to put
"barriers" in the path of his students. Creating "drop off" points,
where the student is tested, and may fall by the fourth way "wayside".
No pun intended. Lord John Pentland said that in the work, people
come in by the front door, and leave by the back door.

Part of the way of development that one does need to contend with
in oneself, is the growth of negative areas, resentments, jealously,
energies that build, almost unbeknownst to one. Then one day,
they can jump out and surprise one. Part of the game.
