I am a newly raised MM. I plan on pursuing my masonic travels in the future. What are the difference between SR and YR?
The two major "lineages" of masonry are the two rites, Scottish and York. Texas masonry follows the York lineage and the Blue Lodge degrees are in fact the first three York Rite degrees. If you take your remaining York Rite degrees, you'll see the same form of degrees that convey "the rest of the story" that you began in your EA, FC, and MM.
The Scottish Rite degrees - coming from a different lineage - are portrayed through a different- beautiful, but different- form. In Texas, the Scottish Rite recognizes the Blue Lodge degrees and accepts them as your first three degrees, but be aware, in some states - Louisiana being one - the Scottish Rite in some valleys also confer the true first three degrees of the Scottish Rite; the first through the 32nd. If you are in Texas and join the Scottish Rite, you pick up the degree work at the 4th degree.
Everyone develops their own preference (York or Scottish) and some do both. Having done both myself, I find myself drawn to the York Rite since it is the completion of the Blue Lodge (EA, FC, MM) "story". Others are drawn to the beauty and form of the Scottish Rite degrees. You may actually find you'll want to try - and therefore join - both to see which you prefer.
