One-on-one lessons involve an intensive, personal approach to the student for one-time lessons or an entire course of instruction. If your student so desires, this training format can allow you to make him into a professional practitioner of out-of-body experience who has mastered it in all its aspects.
When, where, how long, and at what cost the lessons are to be provided are issues for you to decide individually with your budding practitioner. However, the lessons should not be too long or boring, nor take place when the student is quite busy with work or other affairs. Since one-on-one lesson clients are often well-to-do, famous, and/or influential people, you will want to take their busy schedules into account and adapt your methodologies to their needs.
