The clan essence is mentioned in a very clear way in the ancient text because it was important in the tradition. It’s associated to the initiation rituals. The initial fact became a tradition with impact even to others. This tradition has evolved and after the evolution, it became the core of an extended revision which valorized the properties of the subtle bodies. But the idea remains the same as a code in the next centuries. Many people don’t know even the initial ritual which explains the next steps. But the ancient text didn’t forget the essence of the tradition and knows the reality of the past.
