Oath is an announcement or promise made in the name of truth that also summons supernatural forces to invoke a punishment should the statement be incorrect or broken. Christians may make an oath on the Bible, invoking God; Muslims can make an oath in the name of Allah. In occultism oaths of secrecy are frequently part of an organizational initiation ceremony. Should such an oath be broken and subsequently secret truths revealed it is believed that a “psychic current” rebounds upon the practitioner in question by the way of a punishment.
Oaths may also be viewed as men’s way of seeking higher powers to testify to their honesty or keeping them honest. The latter indicates that men do not trust each other integrity. A remedy for this is for each man to increase respect for the truth within himself which builds self-confidence. A.G.H
