The Bhakti movement was a significant religious movement in medieval Hinduism that sought to bring religious reforms to all strata of society by adopting the method of devotion to achieve salvation. Originating in Tamilakam during 6th century CE, it gained prominence through the poems and teachings of the Vaishnava Alvars and Shaiva Nayanars before spreading northwards. It swept over east and north India from the 15th century onwards, reaching its zenith between the 15th and 17th century CE.
The Bhakti movement regionally developed around different gods and goddesses, and some sub-sects were Vaishnavism (Vishnu), Shaivism (Shiva), Shaktism (Shakti goddesses), and Smartism. Bhakti movement preached using the local languages so that the message reached the masses. The movement was inspired by many poet-saints, who championed a wide range of philosophical positions ranging from theistic dualism of Dvaita to absolute monism of Advaita Vedanta.
The movement has traditionally been considered an influential social reformation in Hinduism in that it provided an individual-focused alternative path to spirituality regardless of one's birth or gender. Contemporary scholars question whether the Bhakti movement ever was a reform or rebellion of any kind. They suggest the Bhakti movement was a revival, reworking, and recontextualization of ancient Vedic traditions.
The Sanskrit word bhakti is derived from the root bhaj, which means "divide, share, partake, participate, to belong to". The word also means "attachment, devotion to, fondness for, homage, faith or love, worship, piety to something as a spiritual, religious principle or means of salvation".
The meaning of the term Bhakti is analogous to but different from Kama. The Kama connotes emotional connection, sometimes with sensual devotion and erotic love. Bhakti, in contrast, is spiritual, a love and devotion to religious concepts or principles, that engages both emotion and intellection. Karen Pechelis states that the word Bhakti should not be understood as uncritical emotion, but as committed engagement.
