At Thiruvairanikulam, on the banks of the Periyar near Aluva, Lord Shiva and Goddess Parvati are enshrined side by side — but while the Mahadeva's sanctum is open through the year, the nada (door) of the Parvati shrine is kept closed except for twelve days. Tradition holds that the goddess here is present in her domestic fullness, dwelling with her Lord as in a household, and that her door was ordained to open only around Thiruvathira in Dhanu — Thiruvathira being the star day especially sacred to Shiva and beloved of Kerala's women, who keep its vrata for happy married life. The sthala tradition links the temple's origin to the revered Akavoor Mana family, through whose devotion the deities are said to have come to dwell here. The rarity of the darshan has made Nadathurappu one of Kerala's most keenly awaited temple events.

The Nadathurappu begins when the Parvati nada is ceremonially opened on Thiruvathira day in Dhanu, and for the following twelve days a continuous river of devotees — very largely women — files through for darshan. Pilgrims pray above all for saumangalya, the blessing of a long and harmonious married life, and unmarried women pray for a good and timely marriage; many families come with daughters of marriageable age. Offerings associated with the goddess and with household well-being are made, alongside the temple's regular poojas to Mahadeva. Queues form from the small hours, and the temple and district authorities organise the flow of pilgrims through the festival days. On the twelfth day the door is closed again with due rites, not to open until the next Dhanu — a rhythm that gives every darshan the weight of a full year's waiting.

For Malayali households in Ottawa, the Nadathurappu season can be honoured even from afar. The natural anchor is Thiruvathira itself: women in Kerala keep the Thiruvathira vrata in Dhanu with fasting, songs and the graceful Thiruvathirakali dance, and a Canadian home can mark the same day with a lamp, a Parvati–Shiva prayer and, where friends gather, the traditional songs. Those with a personal vow to the Thiruvairanikulam Devi often ask relatives in Kerala to make offerings on their behalf during the twelve days, or plan a December–January visit to join the darshan queue in person — note that Dhanu falls in deep Canadian winter, so the pilgrimage doubles as a warm homecoming. Live streams and news coverage of the opening day are widely shared each year.
