Our predecessors do not leave us wanting here, either. Repetition of procedure may be seen among modern Catholics who celebrate their Mass daily and weekly. Enhancement is the use of subtle variation within the repetition to keep the paradigm from solidifying before assimilation is complete. The myriad celebrations of seasons provide a constant source of variation in ritual. Costume apparel may change, different aspects of the rite may be focused upon via candles in number and color, different types of music played, etc.
Reinforcers are constant reminders of initiation and can play a role certainly in repetition.
Without resorting to physical scarring, some western European Christian sects are fond of particular clothing on a consistent basis to reaffirm their experiences. The use of reinforcers can bear directly or indirectly on the initiation. This outline of initiatory procedure will, hopefully, find its way into your philosophic armory. Use it to help break down the rituals you use and witness. Notice where the induction takes place, where the teaching and where and how assimilation and analysis is performed.
