Mahāsthāna—Mahāsthāna gada in the district of Bagura in Bengal (Devī Bhāgavata, VII, ch 38). It contained the celebrated temple of Mahādeva called Ugramādhava at the time of Vallala Sena, king of Gauda (Ananda Bhaṭṭa's Vallala charitam, ch VI). It is seven miles to the north of Bogra (town). See Ballālapuri. Its ancient name was Śila Dhāpa (Śila Dhātugarbha) and contained four Buddhist stupas, but the name was changed into Śila Dvipa after the revival of Hinduism (List of Ancient Monuments of Bengal in JASB, 1875, p 183).
