The Bhagavata Purana is text associated with the Bhakti movement which elaborates the concept of bhakti as found in the Bhagavad Gita.The Bhakti movement reached North India in the Delhi Sultanate and throughout the Mughal era contributed significantly to the characteristics of Hinduism as the religion of the general population under the rule of a Muslim elite. After their encounter with the expanding Islam religion, Bhakti proponents—who were traditionally called "saints"—"elaborated egalitarian doctrine that transcended the caste system and encouraged individuals to seek personal union with the divine." Its influence also spread to other religions during this period, and became an integral aspect of Hindu culture and society in the modern era
