About Ganesha's elephant head-Once Parvati, Ganesha's mother was taking a bath. She ordered Ganesha to guard the area and not to allow anybody to enter the guarded area. Shankar, father of Ganesha wanted to see Parvati but Ganesha tried to prevent him. This enraged Shankar who beheaded Ganesha. Seeing this Parvati urged Shankar to attach Ganesha's head. As Ganesha's head was severed Shankar attached the head of elephant who was the nearest animal in the vicinity.
