The most important event at Sabarimala is the Makara Jyothi (usually on January 14th). Thiruvabharanam or the sacred jewels of the Lord (presented by the Pandalam king) arrives at Sabarimala in three boxes. On the arrival of the jewel boxes the whole mountain reverberates to the chanting of 'Saranam Ayyappa' by millions of devotees gathered there to watch the event.
The Thiruvabharanam box - still the private property of the Pandalam royal family, starts its journey two days before Makara Jyothi day from Pandalam. The person who carries the box dances in a peculiar trance. Thiruvabharanam travels through Valiakoikkal Sastha temple at Pandalam, Ayiroor Puthia Kavu Temple, Perunattil temple, Vlakkai, Nilaikkal Siva temple, Vellachimala, Pamba and Sabari Peedam before reaching at Sannidhanam around 6.00 PM on the Makara Jyothi day. Every year a Garuda hovers and flies above the Thiruvabharanam boxes as if to guard them.
On reaching the Sannidhanam the Melshanthi and Thandhri receive the sacred jewels amidst the thundering echoes of Sarana ghosham.
The Thiruvabharanam box contains a diamond crown, golden bracelets, necklaces and a sword. The priests adorn the Lord with these and perform arathi.
At the same moment a brilliant light of amazing magnificence appears in the northeastern side to the temple at the opposite mountain in a place called Kantamala (the home of devas and rishis). It is believed that this brilliant flame of light is the arathi performed by the rishis and the devas. This event marks the culmination of the pilgrimage to Sabarimala.
After the jyothi, that night Malikappurathuamma, mounted on an elephant comes in a procession to the Patinettampadi (18 steps ) and returns back to her abode. This is the beginning of the Makara Vilakku festival. This festival lasts for seven days. Many pilgrims stay back till this festival is over and Kuruthi pooja (offering of water mixed with chunnambu and turmeric powder to the forest deities) is performed.
Even some who leave Sabarimala after witnessing the Jothi observe fasting till the Makara Villaku and Kuruthi pooja is complete at Sabarimala.
Onam, Mandalapooja, Pankuni Uthram (Lord’s Birthday) and Vishu are the other festivals celebrated at Sabarimala with pomp and glory.
