Since at least the seventh century A.D., the devotional path has spread from the south throughout India through the literary and musical activities of saints who have been some of the most important representatives of regional languages and traditions. The hymns of these saints and their successors, mostly in vernacular forms, are memorized and performed at all levels of society. Every state in India has its own bhakti tradition and poets who are studied and revered. In Tamil Nadu, groups called Nayanmars (devotees of Shiva) and Alwars (devotees of Vishnu) were composing beautiful poetry in the Tamil language as early as the sixth century. In Bengal one of the greatest poets was Chaitanya (1485-1536), who spent much of his life in a state of mystical ecstasy. One of the greatest North Indian saints was Kabir (ca. 1440-1518), a common leatherworker who stressed faith in God without devotion to images, rituals, or scriptures. Among female poets, Princess Mirabai (ca. 1498-1546) from Rajasthan stands out as one whose love for Krishna was so intense that she suffered persecution for her public singing and dancing for the lord. A recurring motif that emerges from the poetry and the hagiographies of these saints is the equality of all men and women before God and the ability of people from all castes and occupations to find their way to union with God if they have enough faith and devotion. In this sense, the bhakti tradition serves as one of the equalizing forces in Indian society and culture.
