WHAT IS THE PURPOSE OF ADVANCED SCIENTOLOGY RELIGIOUS RETREATS?

Advanced Organization Los Angeles, California
In Scientology, some upper levels of spiritual counseling require the parishioner’s full-time participation for a period of several weeks in order for the person to achieve the full spiritual benefits of the religious service. Thus, the Church maintains religious retreats, away from everyday distractions. These retreats provide the ideal environment for advanced religious studies and spiritual counseling. While freedom from distraction is important during all counseling, it is vital at the most advanced levels.
