Ganesha is known as the remover of obstacles. In the past I would pray to Ganesha to remove my obstacles until one day I had a revelation… It is not the obstacle that I need removed but my perception that something is an obstacle in the first place!
The idea of obstacles only arises when we believe that something should look some other way, and it is the obstacle that prevents us from getting "there". When we learn to embrace the moment exactly as it is, obstacles transform into "opportunities". Obstacles are then embraced rather than avoided, and seen as part of the journey rather than an impediment on the path.
Here is a Ganesha mantra & affirmation you can try:
Om Gum Ganapataye Namah: “What I perceived to be an obstacle, I now see as a gift of grace!”
