JWG used to teach that the majority of Souls come into any given life by acting out their past in a variety of ways where that past in not only the past of the current life leading the to first Saturn return, but the past history of the Soul itself which of course in symbolized by the EA paradigm in any chart. Because of this most Souls do not make the the choices early in their life that reflect the core EA intentions for the life being lived. This is why the first Saturn return for most can be such a difficult time because many Souls begin to realize that their life to date, the choices made, have not been in accordance with the underlying intentions for the current life. Thus, the first Saturn return gives the Soul the opportunity to make the necessary adjustments that will reflect the underlying intentions for the current life. The key word here is 'opportunity'. Even though such an opportunity exists at that time many Souls do not make those choices to adjust their life anyway because of the nature of their existing 'reality', Saturn, at that time: the structural nature of the reality that has been created to date.
For those that do make the necessary adjustments to their reality that do honor the underlying intentions for the current life then this can lead an acceleration of those Soul's ongoing evolution through time. For those that don't the evolutionary intentions will be actualized is a very slow, minimal way in a variety of ways. This can occur through the internalization of the Soul's consciousness via that common frustration that Soul's feel at the time of the Saturn return: "if I had only done this or that, or gee I would really like to be doing that', and so on. These internalization of the consciousness at that time that leads to these sorts of inner realizations do serve as 'seed thoughts', desires, that will become active at some time in the future for such Soul's.
For the Souls who have made the choices earlier in their life, prior to the first Saturn return, that reflects the EA intentions for the life, then the first Saturn return can serve as the timing for actualizing what the Soul has been preparing itself for. JWG was informed at 24, his second Jupiter return, as to the nature of the life he was to lead. And that included becoming as astrologer. From 24 right up to the time of his first Saturn return he did learn astrology in his own way, and did charts for free so as to learn as much as he could though observation and correlation. To the very day his Saturn return occurred he was offered a job as being an astrologer for a brand new astrology bookstore in Seattle, Wa.
