Sankardeva is undoubtedly an architect of Assam and the greatest personality of all the times. Sankardeva and his legacy are still binding and building the people of the particular geographical location as the Assamese community. Sankardeva is a nationalist person, not religious. But he had to walk on the path of religion in the dark and dogmatic society of medieval India to reach the goal. Through his philosophy and actions, Sankardeva not only transformed the religious landscape of Assam but also influenced its social, cultural, and artistic traditions. Most importantly we try to highlight here Sankardeva's tactical and prudent outlook on Neo–Vaishnavism. He adjusted religious norms on circumstances relaxing the rigidity. Nationalism always defeats theocracy. Religion can't be a matter ultimately. Therefore he hasn't propounded any religion or theory like monotheism or qualified monotheism, pure monotheism etc. like the other Bhakti saints. The socio–political situation or economic condition of Sankardeva's time drives his thought irrespective of religion. Sankardeva exercised democracy in a multi ethnic society, the remotest from mainland India. He was to raise Pan–Indian nationalism through literature in the name of “Bharatbarsha”. His artistic expressions bridged the gap between intellectual reformative teaching and everyday life. That fosters deeper engagement and emotional connection to break down rigid social structure. We see the Bhakti movement is a spontaneous social outburst of the oppressed. As the theme of the book we try to evaluate Sankardeva and Neo–Vaishnavism in socio–political perspective of India sidelining religion. The core aspect of Sankardeva is only inclusivity and social equality to empower marginalized communities. His legacy continues to have a profound impact on Assamese Society.
