Ganapathi Puja should be implemented on all possible auspicious occasions be it starting a new project or even a birthday.
In Hindu culture, Ganapati or Lord Ganesha is always worshipped before starting any Pooja or Homam without fail. Lord Ganapathy eradicates all difficulties encountered by an individual.
Before starting any new venture or anything afresh, it is essential that Ganesh Puja is carried out. That is why in Hindu culture to start something new is also expressed by saying “Shree Ganesh karna”. If one is suffering from failure due to the losses, while starting a new business or investments or when one is planning for getting married, or to remove obstacles or for celebration of your or your child's birthday, Maha Ganpathi Puja is suggested. It is done to remove obstacles, for graha pravesham.
