The "Agni Purana" prescribes that Varaha be in the north-east direction in Vishnu temples or worship. Installation of the icon of Varaha is said to bestow one with sovereignty, prosperity and "moksha" (emancipation). The "Narada Purana" mentions Varaha's mantra "Om namo Bhagavate Varaharupaya Bhurbhuvassvah pataye Bhupatitvam me dehi dadapaya svaha" and recommends Varaha to be worshipped for kingship. A shorter mantra "Om bhu varahay namah" is also given for gaining peosperity. Varaha is prescribed to be worshipped for "ucchatana" (eradication) of foes, ghosts, poison, disease and "evil planets". The one-syllabed mantra "hum" for Varaha is also noted. The "Bhagavata Purana" invokes Varaha for protection while travelling. The "Venkatacala Mahatmya" of the "Skanda Purana" mentions the mantra of Varaha as "Om Namah Srivarahaya Dharanyuddharanaya Ca Svaha" ("Saluation to Varaha who lifted the Earth"). The "Agni Purana" and the "Garuda Purana" associate the mantra "Bhuh" with Varaha. The "Garuda Purana" recommends the worship of Varaha for sovereignty. A "vrata" involving the worship of a gold Varaha image on ekadashi (eleventh lunar day) in bright half of Magha month (i.e Bhaimi Ekadakshi), is told in the "Garuda Purana" and the "Narada Purana". Varaha Jayanti, the birthday of Varaha, is celebrated on the third lunar day in the bright fortnight of the Bhadrapada month. The worship of Varaha and overnight vigil (jagran) with Vishnu tales being told are prescribed on this day. The "Vishnu Sahasranama" embedded in the thirteenth Book "Anushasana Parva" of the epic is a hymn listing the thousand names of Vishnu. The Varaha legend is alluded to in the following epithets: "Mahibharta" ("husband of the earth"), "Dharanidara" ("one who upholds the earth", may also refer to other Vishnu forms - Kurma, Shesha or Vishnu in general), "Maha-varaha" ("the great boar"), "Kundara" ("One who pierced the earth"), "Brihadrupa" ("who takes form of a boar"), "Yajnanga" ("whose body is "yajna" or sacrifice) and "Vaikhana" ("one who dug the earth").
