Should I do group or individual Rebirthing sessions?

Group Rebirthing Breathwork is low quality work. Rebirthing breathing is so simple and powerful that anyone who learns it can induce it in individuals or groups. However, as a result of teaching it for over 27 years, I myself cannot guide the breathing rhythm of more than one person at a time. Therefore, I never do group Rebirthing, nor do I recommend it to anyone.
