In the above quotation, Cayce can be interpreted as saying, do not use astrology as a machine to achieve certain outcomes, objectives or things by relying on it exclusively outside of your own innate inner knowing, belief, persuasion, understanding, gifts, conscience, guides, morals or other tools of self analysis and evaluation. Man, know thyself. You are the master. You are not the slave. Astrology must serve you. You must not serve astrology. We are here to serve, help. It means that you must take responsibility for your actions and decisions. In this regard, astrology can be consulted and used as a guide or portal to open your awareness, understanding and perception to help you to make better decisions or to come to a better understanding of an event, circumstance or situation, but in the end, you must decide for you alone is responsible.
