If there is one ruler that can harmonize and unify the mob of characters [in our astral body], it is the Ego (the Higher Ego, or Self, or Spirit). The more the Ego shines like a sun at the center of gravity of the astral body, the more the different characters start orbiting around it. Instead of working only to satisfy their own selfish desires, the characters start manifesting the purposes of the light and of the Spirit. Instead of plotting for the success of their own ambitions, they start accomplishing the works of the Higher Self... The unveiling of the Self begins a process of unification--a new astral body slowly develops. In this new, or transformed, astral body, the different parts are penetrated by the light of the Self. Therefore they are not only united around the Self, but are also cemented to it... [Before this process], one is nothing more than an appearance: it is the illusion of being one person...
