Looking into Masonry I've found that after one become a 3rd degree master mason he can move up, but it is my understanding that he has to chose Scottish Rite or York Rite. Why is this? Why can't he do both? How come Scottish Rite goes from 4th degree to 33rd degree but York Rite doesn't have numbered degrees and there are much fewer "steps" in between the lowest "step" (Mark Master) and the highest "step" (Order of Knights Templar)? From talking to Masons, reading books and forums like this one, it seems like more masons tend to continue their journey in the Scottish Right rather then the York Rite. Why is this? Please forgive me if I used the wrong terminology.
