During the ceremony of initiation, the candidate is required to undertake an obligation, swearing on the religious volume sacred to his personal faith to do good as a Mason. In the course of three degrees, Masons will promise to keep the secrets of their degree from lower degrees and outsiders, as far as practicality and the law permit, and to support a fellow Mason in distress. There is formal instruction as to the duties of a Freemason, but on the whole, Freemasons are left to explore the craft in the manner they find most satisfying. Some will simply enjoy the dramatics, or the management and administration of the lodge, others will explore the history, ritual and symbolism of the craft, others will focus their involvement on their Lodge's social side, perhaps in association with other lodges, while still others will concentrate on the lodge's charitable functions.
