This is a very popular prayer to Lord Ganesha, typically chanted at the beginning of any new undertaking or even any activity, where we seek Lord Ganesha’s blessings to pave the way for our desired undertaking to happen.
This prayer can be chanted upon waking as well. The time or activity is less important. The sincerity with which we pray is what matters
