Ganesha mantra sounds like OM GAM GANAPATAYE NAMAHA. This means "Om, bow to you, Lord of the Gans"
and is considered as “A greeting to Ganesha, who removes obstacles”
Ganesha (also known as Ganesa or Ganapati) is one of the most important gods in Hindu mythology and he is also worshiped in Jainism and Buddhism. For the Ganapatya Hindu sect, Ganesha is the most important deity. Ganesha is highly recognizable with his elephant head and human body, representing the soul (atman) and the physical (maya) respectively. He is also the patron of writers, travelers, students, commerce, and new projects (for which he removes obstacles from one's path) and is rather fond of sweets, to the slight detriment of his figure.
