Mystical trainings are usually personal trainings, more often of a psychotherapeutic plan, where it is assumed that turning to the Other World will help us solve our problems here. If these are trainings of a developing plan, then they develop not skills, but the divine essence.
Personal trainings in this direction are personal growth trainings, but not personal development trainings. Example: Lev Teternikov.
Apparently, the Hellinger constellations still belong to the trainings of the mystical direction. The spirits of the ancestors that live in the subtle field around us are colleagues, this is an obvious mysticism.
