Soon lord Shiva returned home and the dutiful Ganesha, not knowing Shiva, blocked his path and refused to let him in. Lord Shiva, the supreme trinity who never had his path blocked by anyone, was furious and cut off the head of Ganesha and entered the house.
Needless to say that goddess Parvati made a scene! To appease her Shiva wanted to bring Ganesha back to life. Unfortunately the chopped off head was nowhere to be seen. With the goddess making a racket behind him, lord Shiva asked his men to go in the northern direction and bring the head of the first living being the can find. They soon returned with the head of an elephant. Shiva attached the head to Ganesha's body and brought him back to life.
The ruling deity of astrology, he is also the lord of learning and the lord of obstacles-hence the name Vighnaraja. When pleased he removes the obstacles from your path on auspicious occasions and creates obstacles on inauspicious occasions, and vice versa when displeased.
