Siddhi Valagam

Siddhi Valagam is a small sacred building in Mettukuppam near Vadalur in Cuddalore district, Tamil Nadu, associated with 19th-century saint Ramalinga Adigal (Vallalar). It is the room where he is believed to have locked himself in 1874 and merged with divine light (Jothi). Revered by followers of Samarasa Suddha Sanmarga, the site is maintained as a memorial shrine and pilgrimage centre near the Satya Gnana Sabhai he founded.

Visitors can expect a modest, single-storey building with a locked inner room that is revered as the place where Vallalar attained Jothi. The site is simple and quiet, with an oil lamp kept burning, portraits and information about Vallalar, and a small courtyard. The surroundings are rural and calm, close to agricultural fields and the town of Vadalur. Visitors typically offer prayers, meditate briefly, and view the exterior of the sanctified room.

Siddhi Valagam is historically associated with Ramalinga Adigal (1823-1874), known as Vallalar, a Tamil saint, poet and founder of Samarasa Suddha Sanmarga. On 30 January 1874, he is believed to have entered a room in this building in Mettukuppam, locked it from inside, and attained Siddhi by merging with divine light (Jothi). The building has since been preserved as a memorial to his life and teachings.

The site is highly revered by followers of Samarasa Suddha Sanmarga and devotees of Vallalar. It represents the principles of compassion towards all living beings (Jeeva Karunyam) and worship of formless divine light (Arutperunjothi). Pilgrims visit to pay respects, meditate and participate in commemorative events, especially during Thai Poosam, which marks Vallalar's Jothi Darshan.
