There
is a very big misunderstanding in people regarding astrologers and
doctors. They think the doctors cannot fall ill and astrologer do not
have bad period in their life, because doctors are masters of medicines
and astrologer are masters in remedies.
God
has not given power to any human being ( accept Saints and Sadhus ) to
alter his future. Future written by Vidhata at the time of birth is fix
and final. The position of the nine planets in our kundli / horoscope decides speaks about our destiny. It is also said in some texts that our destiny in this life is due to our karma of our past life ( Previous birth ). We cannot alter it.
Astrology
helps only in minimizing the negative effect of the planets but cannot
completely remove it. It is applicable to an astrologer also, they are
not above human race.
If the power of
altering the future comes in human hand then people will start misusing
it and thus will lead to destruction of the world.
