The Hindu festival of Gajan sees devotees across India celebrate deities such as Lord Shiva, Neel and Dharmathakur. Lasting for one month, the festival culminates on Chaitra Sankranti, the last day of the Bengali calendar. The central theme of Gajan is to derive satisfaction through pain, devotion and sacrifice, with the hope of winning the favour of Shiva, the Hindu God of destruction, whose role is to destroy the universe in order to recreate it.
