The Technical Bulletins , the books and most of Hubbard's tapes deal with the procedures of counselling. Most of the Church's public see mainly these issues, and either receive auditing or train to become auditors. Policy Letters deal with the Organization. Many are unavailable to the public Scientologist, or indeed to anyone without a high enough position in the Organization for which the directive was written. So there are B-1 directives which were only available to individuals who had passed through a stringent series of filters.
Individuals evaluate information differently, selecting different priorities.
In such a quantity of material, there is usually a preferable opinion, which can be used either to avoid or to enforce an excessive rule.

He wrote many short essays for release in Scientology magazines in the 1950s and 1960s. And the true sign of sanity and greatness is to so continue.
