According to historical accounts, approximately 1,600 years ago, an Agnihotri performed 99 yajnas at this sacred site. The revered Shivling in the temple is believed to have emerged from the Homakundam of one of these yajnas. The sand from Thrithala Yajneshwaram Temple, known as Agnihotri Veedhiyile Mannu, holds great significance in Kerala temple rituals, particularly during Brahmakalasham and Parikalasham. The temple is also a prominent site for performing Bali Tharpanam on Karthuvavu or Amavasya days in the Karkidakam and Thula months. Situated on the banks of the Bharathapuzha River in Thrithala, Palakkad district, Kerala, the temple is also known as Yajneshwaram Mahadeva Temple. The Shivling enshrined here is
more Swayambhu (self-manifested). Both deities are housed in a circular sanctum sanctorum (Vatta Sreekovil). Daily puja is conducted only once, and abhishekam is performed using water from the Bharathapuzha River.
