• The Bhakti movement refers to the trend that was brought forward by a number of Hindu saints in medieval Hinduism that sought to bring religious reforms by adopting the method of devotion to achieve salvation. It was prominent in eighth-century south India (now Tamil Nadu and Kerala states), and spread 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. It later acted as the de facto catalyst to the formation of Sikhism. 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.
