This is one of the most popular prayers offered to Lord Ganesha. Ganesha is the God of obstacles. However not many people do not know the following:
When pleased with you, he removes the obstacles from your path when you are on an auspicious undertaking.
On the other hand, when you are on a wrong or harmful mission he creates obstacles so that you fail and are saved!!
Hence the prayer:
Shree Vakratunda mahakaya koti soorya samaprabha,
nirvighnam kurumedeva shubha karyeshu sarvada.
” O lord with the twisted trunk, with the effulgence of a billion suns, always remove the obstacles when I am on an auspicious undertaking.”
