Ucchista Ganapati is the 8th form among the Lord Ganesha’s 32 forms. Many websites & modern books described this Ganesha form as an exclusive Tantric deity form (associated with unclean things like orts, whose worship belongs to vamachara). But it is not true as per an ancient scripture known as “Ucchista Ganapathi Puja Vidhanam’.
The scripture explains the puja procedure in detail along with all slokas & mantrams. Ucchista Ganapati is also mentioned in 16 types of Ganesha (Shodasha Ganapati). But this form of Ganesha is not included in Ekavimsathi Ganesha forms (21 forms of Lord Ganesha).
Appearance & Iconography of Ucchista Ganapathi
