History
Mannarasala is generally described as an ancient temple of considerable antiquity, its origins reaching back many centuries and bound up with the very old Kerala practice of maintaining sacred serpent groves. Precise founding dates are not securely documented, and much of what is known comes through the traditions of the Mannarasala Illam and long-standing devotional accounts rather than dated inscriptions.
The sacred grove is the heart of the site. Rather than being cleared for construction, the kavu has been preserved as a wooded sanctuary in which the serpent idols stand among living trees, reflecting the ecological ethos of the traditional Kerala sarpakavu, where groves were left undisturbed as the abode of the Nagas. The figure commonly given for the serpent images is around thirty thousand, accumulated over generations as votive installations by devotee families.
The temple’s governance by the Mannarasala Illam, a Namboodiri Brahmin family, and its distinctive female priesthood are among its most historically notable features. The office of the Valia Amma — a woman serving as the temple’s chief priest and the custodian of its serpent worship — is widely cited as a rare, perhaps singular, arrangement among Kerala’s major temples, and it is closely tied to the family’s founding legend of the divine serpent son.
Ritual practice has long included the votive offering of the uruli by couples seeking children, together with snake-worship rites such as Sarpabali. The great Sarpam Pattu, the serpent song, is ordained by the temple to be conducted once every forty-one years — a specific interval the temple states plainly, not the vaguer “once in many decades” that circulates. It should not be confused with the Pulasarpam Pattu, which is an annual observance held at Pulakkavu, a sacred grove north-east of the Illam, on the Kumbham Ayilyam or the Ayilyam following it.
The office of the Valia Amma is not a vague tradition but a documented succession with dates. Divyashri Savithiri Antherjanam held it from 1916 to 1993 — seventy-seven years. Divyashri Umadevi Antherjanam followed from 1993 to 2023. The present incumbent is Divyashri Savithri Antherjanam. The office passes to the senior-most Brahmin lady of the family, who must live as a Brahmacharini, and the days on which she alone enters the inner sanctum are fixed: the first day of every Malayalam month, every monthly Pooyam, from the beginning of Magha until the eve of Sivaratri, Thiruvonam in Chingam, the first twelve days of Karkitakam, and the twelve days preceding Ayilyam in Kanni and Thulam. Her death rites are prescribed too — the body laid in the four-chambered hall of the Illam, cremation in a designated place between temple and Illam, and for three days the temple offering reduced to milk and kadali fruit alone, the Palum Pazhavum Nivedyam, with the doors closing immediately after.
The Thulam Ayilyam owes its precedence to an accident of court scheduling. Kanni Ayilyam was originally the principal day, and the Maharaja of Travancore made an annual pilgrimage on it. One year the royal journey was delayed and the visit deferred to the Thulam Ayilyam; in atonement the palace met the entire cost of that year's celebration and endowed the temple with extensive tax-free lands to secure the festival's future. The larger of the two festivals is therefore the second one, and it is larger because a king was late.
Today Mannarasala functions as both a living centre of Naga devotion and a well-known heritage destination, promoted by Kerala Tourism and visited by pilgrims and travellers alike. Visitors are asked to respect its character as an active place of worship and a protected sacred grove, observing local customs regarding access, dress and photography (confirm current rules on site).
