nature is doer not self.

parkarti 'va ca karmani,kiryamanani sarvasah,
yah pasyati tatha tmanam,akartaram,sa pasyati.--28

He who sees that all actions are done only by nature[parkarti]and likewise that the self is not the doer,he verily sees.
All actions of our life are pre-planed.according to astrology this is not random.it is based upon nature's logical conclusion are bound by our previous and present karmas[deeds].that is why planets shed effect on our lives.what we read or write,go to any part of earth,our relationship,our well being,become rich or poor all related to our past lives.our faith is product of field[shetrah]depending upon the seed sown.
But who knows that our self is not doer but he sees of our all actions of body,mind,sense organs[only witness]he sees right.and he also knows that i am is self.seer not seen.witness not witnessed.
