Ganapati Atharvashirsham

Ganapathi Atharva Seersha is a part of Atharva Veda. It is classified as an Upanishad and not as a chant; yet it is considered universally as the greatest and most effective prayer addressed to Lord Ganesha.
It is said that whoever will study and recite this hymn will be free from all the obstacles and will be protected and will progress in Dharma (religion), Artha (wealth), Kama (desire) and Moksha (liberation).
