The temple is also closely associated with the Ramayana. According to local tradition, Lord Rama performed Bali Tharpanam at Aluva in memory of the noble eagle Jatayu while searching for Sita. This sacred association has made Aluva one of Kerala's most important pilgrimage centres for performing ancestral rites. Another cherished tradition relates to the renowned saint Vilwamangalam Swamiyar, who is believed to have rediscovered the ancient Shiva Linga through divine vision. Following the instructions of Lord Shiva, he began regular worship at the shrine with the support of local devotees. Since ritual vessels were unavailable during the early days, offerings were traditionally presented using an areca palm leaf, symbolizing simplicity, humility, and unwavering devotion.
During Aluva Shivaratri, devotees observe fasting, chant the sacred mantra "Om Namah Shivaya," and remain awake throughout the night in prayer, meditation, devotional singing, and scriptural recitations. Special rituals such as Rudrabhishekam and ceremonial offerings of water, milk, and other sacred substances are performed to honour Lord Shiva. The festival represents spiritual awakening, self-discipline, and the triumph of light over darkness.
One of the most significant traditions associated with the festival is Bali Tharpanam, performed on the banks of the Periyar River on the morning following Shivaratri night. Thousands of families gather to offer sacred oblations in memory of their departed ancestors, praying for eternal peace for their souls and blessings for future generations. This centuries-old ritual continues to make Aluva one of the most revered destinations in Kerala for ancestral worship.
The expansive sandbanks of Aluva Manappuram become the centre of the celebrations as temporary stalls, exhibition sheds, and traditional markets are set up for the festival. Visitors can explore stalls selling devotional articles, handicrafts, local products, festive items, and regional delicacies. Throughout the night, classical dance performances, devotional music, traditional temple arts, storytelling sessions, and cultural programmes create a vibrant atmosphere while helping devotees remain awake during the sacred vigil.
Although Maha Shivaratri is the principal day of worship, the temple celebrations continue for nearly a month with a series of religious ceremonies and cultural events. Daily Ezhunnallippu, the ceremonial procession of the deity mounted on a beautifully caparisoned elephant, forms an important part of the festivities. The grand Dikvijayam procession is conducted on the third and fourth days, followed by the traditional Pallivetta ceremony on the fifth day. The annual celebrations conclude with the sacred Aarattu ceremony, marking the ceremonial end of the temple festival.
Today, Aluva Shivaratri stands as one of Kerala's most iconic religious celebrations, bringing together spirituality, mythology, culture, and community participation in a truly remarkable setting. The sacred Periyar River, the unique open-air Shiva Linga, centuries-old legends, and the devotion of countless pilgrims combine to create an unforgettable experience. For pilgrims, cultural enthusiasts, and travellers alike, Aluva Shivaratri offers a unique opportunity to witness one of Kerala's most enduring spiritual traditions while experiencing the rich cultural heritage of God's Own Country.
