Commonly, people discuss these issues using past experience and problems, wanting to inform so that countries or people will act differently. such might be this oddity - they say all cultures come from african origins, so it is only the former africans trying to take back what they had, that is the reborn africans. same might be said for lost atlanteans, now alive today, trying to get back control of the world. still, we are not going to accept reincarnated souls in the purely physical sense as a reasoning for actions or liability. so it is best to let go of the past. or release its hold on us, and think in present, and in principle both.
I prefer to look at consciousness and principles, not to try to point out the differences from the past, or between cultures, but rather to look at themes such as karma, and understand them, so in the present will act in the most positive and best for all concerned, to avoid karma producing actions or behaviorial or national intentions that fit better with a future good. understanding karmic laws makes sense, and is tied to reincarnation as a spiritual principle of life. If all realize they have lived before, and the law of karma has propelled them into current circumstance, they would think to act quite more in line with due diligence.
the law is good equal good, and what goes around comes around, and in astrology terms, they say as above so below. Now I find it is even more as within, so without. this law is that as we are in spirit, and within ourselves, so will we be without. as we belief, so it will come to pass. or the law of what you expect, will persist.
so how do we live in these many laws. the lead is a key term 'ethics'. what is spiritual remains spiritual, and what is physical, is dealt with physically. but the principles work on both levels, in specific to that level. we are both soul, spiritual, and also the human. In astrology, this is that the planets are 1x harmonic act on the physical, but the harmonics are also here, and can be used, such as 60x harmonics, to make sense both to our inner self, and to the outer self, the body and physical person. so we are individuals with spiritual qualities, but also human, this of two levels I mention here in the chart. even so we are really more than just these two, and also a composite, of all we have been before, and of what we will be too.
we use aspects, progressions, et all, which are not strictly accurate in experiential terms, unlike the planets in their courses, yet we use them both, because there is an actuality to them, a place of timing and space measures we can define, even if not a real actuality. for example, jupiter rises in a chart at birth is a correct approximate that the person will be positive, yet we may see the progression of this jupiter to 2nd house, as the person begins to earn money or make special purchases or wealth gained.
of course there is also the jupiter could be excess or fortune, so we cannot predict just on that one factor. so we need to find the specific aspects being most accurate, and the best principles also to live by. we must make choices. this is the free will in the world of karma. some may accept karma, others deny it, and others do not care, while the karma wheel continues. those who would be free know they need also be responsible. then they see the connections, and make better choices.
