What we have to understand is that every time someone joins a club, committee, society, etc they do so based upon their own needs, desires, and goals.
Every time a club, society,committee, etc allows a new member they do so for the good of that group. The Elks, Masons, Rosicrucians, Shriners, are no different. If your goal was to join and help you will only associate with those like you. If you are a bit tinged and join for self aggrandizement you will be successful. That is the purpose of the secrecy.
The original Illuminati I studied were interested in the studies. Later I learned some real truths that made me go a new way.
The same is true for every member of any group who studies the "Secret" way. They arrive at a point when they must decide to go toward the light or to carry the light.
That is the purpose of the lamp lighters. They issue a member toward a place in their being where the must all make this choice. Some however never study and never proceed beyond the door. These have friends, do charitable works, and keep the 9 parking spaces by the side door vacant for special guests.
If you belong to a group and you are doing good work for the brothers, their families, the Community, and the world, may Yahweh bless you.
If you think the secret rites are just a bunch of non-sense to keep you paying dues you are not studying, and haven't reached that place where you need a light, pray for Yahweh's guidance each time you study. He will tell you when to stop.
The biggest secret I learned was that there can be no good unless there is Evil. There can be no salvation unless there is something so vile you must be saved from it by Yahweh.
