Hello aspirant,

Bhakti movement:-

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 as an influential social reformation in Hinduism, and provided an individual-focused alternative path to spirituality regardless of one's birth or gender.

Indian literature:-

Indian literature refers to the literature produced on the Indian subcontinent until 1947 and in the Republic of India thereafter. The Republic of India has 22 officially recognized languages .

The earliest works of Indian literature were orally transmitted. Sanskrit literature begins with the oral literature of the Rig Veda  a collection of literature dating to the period 1500–1200 BCE. The Sanskrit epics Ramayana and Mahabharata were subsequently codified and appeared towards the end of the 2nd millennium BCE.
