Your goal is to begin at the bottom, reach the top and then return with that knowledge and experience, back to the One. This process unfolds over the lifetime of a world and is both of a physical, and spiritual nature. The lifeforce that resides in a physical form is enlarged and matured over the course of many lifetimes. Starting at the single cell level, a lifeform will progress upwardly through increasingly complex biological containers in a process of birth, death and rebirth. It is the evolutionary process of all life, and all life is bound by this law of the One.
Evolution is the creation of a more complex lifeform from less complex lifeforms.
You will work your way up the ladder of life until you reach the point that your spiritual enlightenment is so great that there is no physical lifeform complex enough to contain you. It is at this point that you leave the restrictions of the physical behind, and merge with the other lifeforms who have reached this level. Together, you will form the great collective spirit that is called the One. This is the path you are now on. In terms of progress, you are half-way home.
