We talk about so many nakshatras or grahs ( suriya, rahu , ketu , shani etc) effecting our daily lives is some manner or other , constantly changing our destiny but since future doesn't exist how can destiny , & since you live within NATURE & all these grahs are within the same nature, all around you, so believing that they exist why would they want to interfere with your life , then what will be the use of FREE WILL if these regulate our karma . So even if you can't resist the temptation that there are some grahs controlling your life just close you eyes picture complete darkness in your mind & see a burning OM in the middle , you have summoned all of NATURE within yourself & they will be within your control now & then your FREE WILL will come into the picture .
