This art installation by young Odia artist Smrutikanta Rout depicts Daru Brahma (Neem trees with special attributes used for carving of new idols of Lord Jagannath, Lord Balabhadra, Devi Subhadra and Lord Sudarshan) of Nabakalebara Yatra.
No ordinary Neem tree can be used to make the deities. Certain well defined criteria must be satisfied by the tree before it is labelled a Daru Bramha fit for deities making. Locating the four holy trees requires divine intervention. As per long-standing tradition the Priests of the Jagannath Temple (Puri) worship Maa Mangala at the Kakatpur Mangala Temple. It is said the Goddess appears to them in their dreams revealing the location of the holy trees.
Art installation is an artistic genre of three-dimensional works that are often site-specific and designed to transform the perception of a space. (Wikipedia)
