Ekadanta
According to Puranas, Parashurama travelled to the Himalayas to pay respect to his teacher, Shiva. While travelling, his path was blocked by Ganesha, son of Shiva and Parvati. Parashurama threw his axe at the elephant-god and Ganesha, knowing it had been given to Parashurama by his father, allowed it to sever one of his tusks.
His mother, the goddess Parvati, was infuriated and declared that she would cut off the arms of Parashuram. She took the form of Durgama, becoming omnipotent. At the last moment, Shiva was able to pacify her by making her see Parashurama as her own son. Parashurama also asked her for forgiveness, and she finally relented when Ganesha himself spoke on behalf of the avatar. Parashurama then gave his divine axe to Ganesha and blessed him. Another name for Ganesha because of this encounter is Ekadanta, or 'One Tusk'.
