There are three stages in one’s overall development. There is dependence. There is independence. And there is interdependence. In the simplest way, this is demonstrated in a person’s life by the fact that they are very dependent when they are infants and young children, slowly growing out of dependence to a state of independence as an adolescent or young adult, when they begin to differentiate from their parents and family. Then there is interdependence, when they are married and have a family, or unite with other people in spiritual community and so forth.
You are living in a state of Separation—as a singular person, seemingly distinct from all other singular persons, distinct from other life forms, with a singular identity and awareness.
Your Spiritual Family has everything to do with why you are here in the world at this time. And it has everything to do with the future of humanity and whether humanity as whole and human civilization as a whole will be able to survive and advance in the future.
What is fulfillment? Fulfillment is fulfilling what you came here to do. Only Knowledge knows what you came here to do because Knowledge was put within you by God.
