A question which cannot be answered by Astrology. Even our day to day life is not permanent and how come a govt. job is permanent. No job is permanent and it is God’s command we carry out whenever and whichever place it is.
Astrology can only evaluate a horoscope and give you the success factor of each house all of which together forms the life between birth and death. There will be quite a lot of fluctuations in these success factors based on Mahadasa, Antardasa, Pratyanthardasa etc. up to 6 levels. Read my blog navagrahastro.blogspot.in which will give you a very good idea about all these things.
