When the original Order schismed the tradition went in seperate directions, the Current diverging into many different streams. This brought the tradition to more people, just as tributaries bring water to more land. It allowed the system to grow in multiple ways because it unshackled it from its original constraints. The mystical brought it in one direction, the masonic in another, the magical in yet another. The SM and AO developed two different, yet equally valid, streams from which the GD current could grow exponentially more than would have been possible had they all remained together.
And it is still here, growing, taking new directions. Things are being added and changed, new insights found, new ways of looking at the material of our forefathers, and new material for our children to look upon and discover things we do not know. Tradition is a trade, a give and take, a flux, the intake and outake of breath, for it must be alive or it is a fossil for the eyes of academics. Thus must we not cling to tradition for the sake of it, but help it grow so that it may help us grow in turn.
