Many monks strive to be a master and few ever achieve such a feat. Even fewer achieve Grand master for it is the most difficult path to learn for to learn it you must learn all the other paths to a satisfactory level. Many go on pilgrimage but usually only one returns for many die trying to achieve this goal of being the greatest of monks in history. They must master a single skill of choice from each of the ways of the drunken master, shadow, four elements, kensai , long death, sun soul and open hand. This leads these warriors on a very difficult pilgrimage were their limits are tested and strained. Only the grandest become grand master. Discuss with your DM the ability to use this subclass for it can be broken it should only be used if it fits your character whether from design or circumstance.
