Does a blade of grass wonder what its purpose is? Does a bird wake up, concerned or depressed that it is off-track, without no purpose or meaning in its life? No (as far as we know :O)), they just are. The difference being is that we have the 'gift' of being conscious of our consciousness - we cannot know what it means to be 'connected' unless we have experienced what it is to be 'disconnected'. We cannot know light, unless we knew dark etc etc
Our primary purpose may be to come to be the truth in this lifetime. Discovering such truth does not end the debate. We are still human (otherwise we would not have form, so it is also just as true that we have this limitation to deal with) and we are coming to terms too, with what that means. There is a universal truth within us, a life-force that is one, yet we are all so unique in our human-ness Can we align the two in balance, and in harmony?
