Makara Vilakku Pooja is a seven-day festival conducted annually in the famous Ayyappa Temple at Sabarimala. The festival begins on the auspicious day of Makara Sankranthi, the day on which the sun is in summer solstice (vernal equinox). This is also the first day of the Malayalese month of Makaram. Makara Vilakku Pooja commemorates the day on which idol of Lord Ayyappa or Dharma Sastha was enshrined in the temple and is the most important event to be conducted at Sabarimala. Thousands of devotees gather to participate in the celebrations of Makara Vilakku every year. Mandala Pooja festival extends to 41 days prior to Makara Sankranthi.
One very important ceremony of Makara Villaku is the bringing of deity's jewellery, Thirivabharanam from the Pandalam Palace, three days prior to Makara Sankranthi. The sacred jewelry is kept in a box and is brought in a royal procession. Thousands of devotees line up on either side of the route for a glimpse of the box, which is carried by a priest, or oracle on his head. The oracle moves hysterically oblivious of the presence of thousands of people. He dances, but the box remains on his head as if it gets glued on his head. Procession halts at a few temples en route and reaches Sabaripettam in the evening of Makara Sankranthi. It then moves towards Sannidhanam amidst music, dazzling lights and lot of revelry. A strange phenomenon occurs at this time. A kite appears all of a sudden and starts hovering around the box. The incidence is well received by the devotees who get filled with joy.
The jewelery consists of a diamond crown, gold bracelets and necklaces studded with precious gems, Lord's swords, silver arrows and gold images of elephant, horse and leopard. Thousands gather for that dazzling glimpse of a fully ornamented deity.
The other spectacular event is the appearance of 'Makarajyothi' in the north-east horizon on Ponnambala Medu. Chants of 'Swamiye Saranam Ayyappa' reverberate as the devotees turn ecstatic on the strange occurrence.
Makara Vilakku poojas and ceremonies are performed on the 'Manimandapa' (sacred platform) near the Devi shrine where a picture of Sastha riding on a leopard's back is depicted. After the pooja, Malikappurath Amma is mounted on an elephant's back and carried in a procession comprising of torchbearers, drummers, buglers etc. to Pathinettampadi. The procession halts for sometime and shouts a call for Vettavili (hunting) and returns after circumabulating the main temple.
Festivities continue for seven days and culminate with 'Guruthi'. In this offerings are made to the Lord. The temple is vacated after Guruthi. Nobody remains inside as a tradition.
On the last day of the Makara Vilakku celebrations, which is Makaram 5th morning, a 'Ganapati Homam' is conducted at the temple. Later the Thiruvabharanams are removed. After performing some more rituals the procession makes its return journey along with the Thiruvabharanam.
