Once while Maa Parvati was having bath, Lord Ganesh stood near the door. He did not allow anybody to enter. At that time Lord Shiva came . Lord Ganesh also did not let him in. Lord Shiva did not knew that Lord Ganesh was is own son. A fierce battle was fought between the father and the son. Lord Shiva beheaded him. After returning from her bath, Maa Parvati saw the terrific incident. She told Lord Shiva everthing about Lord Ganesh and pleaded with him to bring Ganesh back to life. All the devas searched for dead body of humanbeing. They could not find any. They found the dead body of an Elephant. They cut the head of that elephant and fixed it into the body of Lord Ganesh.
