The Vaikom Mahadeva Temple, located on the banks of the Vembanad Lake in Vaikom, Kottayam District, is a sight to behold with its stunning Kerala-style architecture. Often referred to as the Dakshinakasi of the south, this temple becomes even more magnificent during the twelve-day Vaikathashtami festival held annually in the Malayalam month of Vrischikam (November/December).

This festival is a grand cultural extravaganza, featuring dance recitals, Kathakali performances, music concerts, and vibrant pageantry that captivate visitors of all ages. The final day, known as Vaikathashtami, is marked by a majestic procession where the thidambu (replica of the presiding deity) is carried on the back of an elephant, accompanied by processions from nearby temples, creating a spectacular visual feast.

The Vaikathashtami festival starts with the Thrikkodiyettu (Holy Flag Hoisting ceremony) and includes various rituals such as Sreebali, Vilakku, and Poothalam Varavu on the fifth, sixth, and seventh days. One of the festival's highlights is the Ashtami Vilakku, where numerous lamps are lit, illuminating the temple grounds. Another significant ritual is the Udayanapurathappante Varavu, where Lord Muruga (Subrahmanya) from the nearby Udayanapuram Subrahmanya Temple comes to pay respects to his father, Lord Shiva, at the Vaikom Temple.

Other festivities include Panchavadyam (traditional percussion ensemble), Gajapooja (worship of elephants), Aanayoottu (feeding of elephants), and various colorful processions. The festival also features a host of cultural programs, including Kathakali performances and musical shows that continue throughout the night. The final day of the festival is especially significant, with Koodipooja Vilakku, Thrikkarthika, Athazhamoottu, and the Arattu ceremony marking the conclusion of the celebrations.

The legend behind Vaikathashtami traces back to a saint named Vyaghrapada, who prayed to Lord Shiva for many years. It is believed that Lord Shiva and his wife Parvathy Devi appeared before him on the day of Krishna Ashtami, which is commemorated through the festival. The Vaikom Mahadeva Temple holds a special place in the hearts of both Shaivaites and Vaishnavites, with its Shiva Linga believed to date back to the Treta Yuga, making it one of Kerala's oldest temples where uninterrupted pooja has been performed since its inception. The festival's deep-rooted traditions, combined with its vibrant cultural displays, make Vaikathashtami a truly unique and spiritually enriching experience.
