It is a love based creative intelligence that underpins the evolution of this universe, the discarnate spirit exists as a combination of love and mind.
Without spirit there can be no life so the spirit enters the new entity at conception. As the embryo develops the spirit hands over direction of its development to the mind. If the spirit were to remain in control the psyche of a human being, it would not have the room to develop and fulfil its destiny on Earth. The spirit therefore relinquishes its influence over all conscious matters giving that task to the growing mind which must learn to make decisions. Mind and will take the initiative allowing the psyche to grow. Will is the energy of thought and mind.
Through the experience of living physically it is hoped that the energy of thought aligns itself to the energy of spirit (love) with mind, spirit and love becoming the living embodiment in a physical world. For this to happen we also have to develop intelligence. It is the union of thought and spirit that lead to wisdom.
A life is lived and until a physical body has to be relinquished because for whatever reason it cannot function adequately in a physical environment. On leaving the physical body the mind reunites with the spirit. Released from its ailments, restrictions and illnesses it moves into a discarnate world of mind that exists outside of physical time and space incorporating all it has experienced.
