After having laid the foundations for a dramatic and meaningful presentation we finally come to the problem of making the Mass operate on a magical level. Certainly there is magick in a ceremony which pleases and teaches i ts audience, but we know that there is also another kind of magick possible. Could the officers but perform these prayers and invocations with their wills as well as their mouths they would experience an explosion of power, imparting reality to the blessing of the sacrament. There will also be increased health and prosperity for the officers and communicants at a ritually effective Mass. Keeping a record of Masses you perform, how they go, and what results, is a good way to track your progress as magicians. A couple of other issues of minor ritual significance should be discussed here.
Most sanctuaries perform one or more banishings before beginning their Masses.
Though Crowley did not, as far as I know, explicitly suggest this practice, he did often do an LBR before partaking of the sacrament, and it does seem advisable. But keep in mind that an improperly performed banishing will often be more disruptive to your Mass than no banishing at all. Avoid using people who are unsure of their ritual to perform the final banishing before a ceremony. There is another ritual custom which has grown up in some sanctuaries. Any strong opposition on the part of officers or communicants can vitiate or destroy the ceremony's magical effectiveness.
