Hariharaputra — the celibate god of Sabarimala
Ayyappa (Malayalam: അയ്യപ്പൻ; also Ayyappan, Sastha, Manikandan) is the presiding deity of Sabarimala, Kerala — the forest-hill shrine that, by annual pilgrim count (approximately 50 million per season), is one of the three largest pilgrimage gatherings in the world alongside the Kumbh Melas and the Hajj. He is the Kerala T0 anchor and sits at the theologically most complex junction in the south Indian pantheon: simultaneously Shaiva (son of Shiva), Vaishnava (son of Mohini, Vishnu's female avatar), Ayyan-Shasta (regional Tamil tribal-god substrate), and Manikandan (the historical / legendary prince of the Pandalam royal family).
The standard Ayyappa myth, as crystallised in the Bhuthanathopakhyana and later Malayalam temple-kathai literature, frames him as the son of Shiva and Mohini (Vishnu's female form), born to destroy the demoness Mahishi and instantiate a vow of brahmacharya (celibacy) that he maintains until the day all women of reproductive age cease visiting his shrine — the theological root of the restriction on women aged 10–50 entering Sabarimala, a restriction overturned by the Indian Supreme Court in September 2018 and since then the subject of continuing legal and political contestation (see Devika 2019).
The historical-genealogical layer of the mythology places Ayyappa as Manikandan, an adopted prince of the Pandalam royal family in the 12th century, who defeats Mahishi, restores dharma, and departs to the forest as a divine avatar — merging the Puranic Dharmashasta tradition with a localised royal lineage in a way that scholars (Sekar 1992) read as a deliberate medieval consolidation.
As described in the Ayyanar entry, Ayyappa is almost certainly a Brahminised, centralised Kerala form of the same Ayyan-Shasta tree that produces the de-centered Tamil village deity Ayyanar — evidence includes the shared yoga-pattam iconography, the meditative seated pose, and the accompanying Karuppa-class guardian (who at Sabarimala is Vavar Swami, a Muslim saint in the vicinity whose inclusion is theologically load-bearing).
The Sabarimala pilgrimage follows a rigorous 41-day vratam preparation:
The Makaravilakku day (14 January) features a controversial "divine light" (Makarajyothi) on the opposite hill — revealed in 2011 by Kerala state authorities to be a man-made fire lit by temple and forest-department staff, an admission that did not diminish pilgrim attendance.
The shrine is administered by the Travancore Devaswom Board, a statutory body of the Kerala government. The Tantric head (Thantri) family is the hereditary Thazhamon Madom; the Melshanti (head priest) is appointed annually by lottery from qualified Brahmin applicants.
The 2018 Supreme Court judgment (Indian Young Lawyers Association v. State of Kerala) declared the ban on women aged 10–50 unconstitutional. The political aftermath — protests, the LDF-led Kerala government's complex handling, BJP counter-mobilisation, subsequent Supreme Court review — has made Sabarimala the most politically salient Hindu temple in contemporary India. Any serious entry on Ayyappa must address this; Devika (2019) and continuing scholarship in the Economic and Political Weekly and Journal of Hindu Studies provide Tier 1 footing.
Ayyappa is the Kerala T0 anchor, the theologically syncretic case par excellence (Shiva + Vishnu-Mohini + Ayyan-Shasta substrate + Vavar/Muslim integration + Pandalam royal lineage), the site of India's most recent major Hindu religious-legal controversy, and the Kerala-side pole of the Ayyan-Shasta lineage whose Tamil pole is the Ayyanar entry.
