The Gatha stones are considered to be auspicious and have an important place in the culture of the tribes. These memorial stones are used to appease the spirits and commemorate the dead. Each stage of the Gatha stone making is accompanied with prayers and ceremonial gatherings. From the day the date is fixed for sculpting, to each stage of the carving and finally the grand installation of the Gatha stone, each and every step of the way is celebrated with elaborate religious rituals. The completed memorial is taken to the village elders for their blessings, followed by a grand feast organized to celebrate the Gatha installation where alcohol is enjoyed liberally.
A ceremonial ritual is conducted to commemorate the placing of the stone, where the sculptor or artisan presides as the priest during the ceremony. Donations of food and clothing are also made
The stones selected for carving are mostly hard, crusted, white stones. A fair sized rock is broken to obtain a flat surface with an even thickness of 10-15 cm. The flat stone surface obtained is worshipped by performing certain rituals, and then work on it begins.
The design to be made is drawn using pencils and charcoal, with the portrait of the person drawn in full detail. Using various sized chisels and hammer, the designs are carved. Depth is added to the sculpture by carving out spaces of about an inch around the figures, this enhances the sculpture making them look life-like. Traditionally, Geru was used to paint the stones in a brick red color, but recently oil paints have also come to be used in painting the sculptures. The carving is often done between, 'Kartik Chaudas' (end of November) and 'Holi', which is celebrated in the middle of March. A peculiar tradition is followed by the artisans where they work on the stones only in the night and not in the mornings. It takes almost a fortnight to carve a Gatha.
