Thirumullappully Mahadeva Temple has an intriguing origin story. Once, what is now the temple grounds served as a grazing field. Legend has it that a village woman while sharpening her sickle on a granite rock, was startled to find blood flowing from it. This peculiar event attracted equally amazed villagers. Seeking answers, they consulted an astrologer who confirmed the presence of the divine Parama Shivan (Mahadevan) in the area, particularly in the form of the angry Thandava Shiva. The backstory unfolds with the tragic tale of Satidevi, daughter of Dakshaprajapathy, who immolated herself in Yoga Agni (sacred fire) due to humiliation at a Yagna (ritual sacrifice) which more her husband, Shiva, was not invited. Learning of her sacrifice, Shiva, consumed by rage, dispatches his divine disciples Bhadrakaali and Veerabhadran to slay Daksha, after which he performs the ferocious Thandava nritham (dance) before entering deep meditation (Dhyana), known as "Dakshinamurthy." In reverence to this divine presence, the villagers resolved to construct a temple. Today, the deity enshrined at Thirumullappully is the angry Lord Shiva, a unique feature shared only with the Kottiyoor temple in Kerala. The majestic temple complex owes its existence to the altruism of ten Namboodiri families from the village, who relinquished their land and wealth for its construction. These families continue to serve as Trustees and Ooraalans (caretakers) of the temple. However, the temple's management has been entrusted to the Malabar Devaswom Board due to resource constraints, ensuring its upkeep and continued reverence.
