The philosophical foundations of Bhakti are laid down in the Narad Bhakti Sutras and Sandilya Bhakti Sutras. The nectar of bhakti hinted at by these texts finds it delightful blossoming in the Srimad Bhagavata Purana.
Among the prominent bhaktas who have inspired generations we may mention: Jnanesvara, The Alwars, Namadeva, Narsi Mehta, Guru Nanak, Mirabai, and Sankara Deva. Great stimulus was given by the bhakti movement to Brajabhasa, a Western Hindi dialect, and also to Awadhi or Kosali, an Eastern Hindi speech. The followers of Sri Chaitanya Mahaprabhu, through their writings, greatly influenced the development of Bengali.
Tulasidasa’s Rama-carita-manasa, an early Awadhi (Eastern Hindi) version of the Ramayana, became a classic in its own right and, for the greater part of northern India, provided the gospel of righteous living in a language of perfect beauty. Suradasa and Mirabai wrote their lyrics on Krishna in Braja-bhasa and Rajasthani.
Here is a collection of bhakti books, suitable for all - whether just entering bhakti, or those who have already made it a way of life.
