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.
