The performance of the Nabakalebara is a very critical and lengthy process. It starts 65 days before the Deba Snana Purnima.
On the 10th day of the Shukla Paksha of the month of Chaitra, i.e., on the day after Rama Navami, after the Madhyannha Dhoopa (afternoon oblations) the Pati Mahapatra, Deula Karana, Tadau Karana, Behera Khuntia, Biswakarma along with Badagrahi Daitas and others offer their due prayers to the Chaturdha Murtis and obtain their permission in the form of Agnyamala (garland of permission). A ceremony of tying the blessed sarees on their head, i.e. Saree-Bandha is performed in the Jagamohan and Natamandir.
"The First step of the Nabakalebara, starts with the Banajaga Jatra"
A group of Daitapatis proceed on this Jatra locate and bring back the Daru Brahma that would make the new bodies, being requested by the Gajapati Maharaja, the first Servitor of the Lord. They proceed to Jagannath Ballav Math on the Grand Road and stay in the Jagannath Ballav Matha for one and a half day for initial preparation. Thus starts their strenous ritual of appeasing Maa Mangala for hints of the sacred Daru Brahma through Swapnadesh. After the Daru Brahma is identified and approved, there are several rituals that grace these ceremonies are Daru Brahma Pujanam, Daru Brahma Snanam and Ankuraropana.
The Daru Brahma are cut first with a golden axe, then with a silver axe and ultimately with an iron axe. The required sized trunk is cut in Chaupata (quadrangular) shape and covered with white silk cloth and loaded on the Daru Brahma Shagadi which is drawn by the people of the places from which they pass on their way to Puri among the sound of ghanta, conch and kahali etc. They are temporarily kept in the Koili Baikuntha in the temporary sheds prepared for this purpose only. Daily Puja and Prasad is offered here till the Deba Snana Purnima.
The last fortnight of the extra Ashadh is the normal Anasara period of the deities. The idols are now in the hands of the Pati Mahapatras, Badagrahi Daitapatis and Dutta Mahapatras who are the Anga Rakshaks of the deities. The new idols are given the final shape with Saptabaran Bidhi. The idols are wrapped with stripes of clothes and applied different preservative and scented materials like some medicinal oils prepared in advance, sandalwood paste, Kasturi (musk), karpur (camphor) etc which act like the veins, blood, muscles, bone marrow etc. During the last two days of the Krushna Paksha the idols are painted by the Dutta Mahapatra which is known as Banaka-lagi of the Lords. They paint the idols with indigenous colours. They leave the pupils for the Brahmin Pujaks to do on the Pratipada or the 1st day of the Shukla Paksha or the bright half of the regular Ashadha. Painting of the pupillary by the Brahmin Pujaks on this day is known as Chakhyu–Dan rite. This day is known as Netroschaba and people have Nabajauban Darshan.
The Lords of Shree Mandir in a new Kalebara are ready for the usual Ratha Yatra or a car festival on the next day.
