We possess the potential to develop consciousness. There is a science with which we may rise out of our given state of relative unconsciousness and grow fully conscious. The science of conscious development consists of a system that can be understood verbally, allegorically and mathematically. The verbal model of conscious development consists of a glossary of terms in English with precise definitions. The allegorical model of conscious development outlines the components of consciousness in the context of a story. The Archetypal story is an allegory of conscious development. The twenty-two Tarot Trumps serve as illustrations to the Archetypal story. The mathematical model of conscious development consists of the Archetypal diagram and the symbols of the nine Laws. The nine Laws constitute a thermodynamic model of conscious development. The Archetypal diagram is a universal analog and a mnemonic device that indicates how the various components of the models relate to one another. The exercise of attention is the essential method of conscious development. By persistently paying attention, by repeatedly touching base with our sense of being present, consciousness develops in stages. The aim of the science of conscious development is full consciousness. Full consciousness is a perfectly proportioned self-sustaining totality, the epitome of Beauty, the immortal soul.
