The Grotto is a social organization for Master Masons only, with the emphasis on the Blue Lodge field.
Masonry deals with manhood, square and upright.
Its lessons are beautifull, dignified and earnest. Within the Grotto is the playground for the Master Masons, the organization has nothing to do with symbolic craft Masonry. Yet theGrotto ritual is the most spectacular, colorfull and elaberate ritual seen anywhere. There is solemn, serious motif. The lesson it teaches invokes the precepts of the Golden Rule.
