It is said about Ganesha that he is the one who gives Riddhi and Siddhis. Gajanan has two wives - Riddhi and Siddhi. Ganesha has two sons named Kshem from Riddhi and Labh from Siddhi. When Kartikeya went to fight with the Asuras in the south and defeated the Asuras in the war, then Lord Shiva named Ganesha's son as Kshem. The eight types of Riddhi-Siddhis are the eight powers that are obtained from the practice of yoga.
