Surdas, blind hindu devotional poet and singer, who was known for his lyrics written in praise of Krishna. Surdas is usually regarded as having taken his inspiration from the teachings of Vallabha Acharya, whom he is supposed to have met in 1510. There are many stories about him, but most consideringly he is said to be blind from his birth. He is said to have become foremost among the poets the Vallabha Sampradaya designates as its (eight seals), following the convention that each poet affixes his oral signature called chap at the end of each composition. However, the absence of Vallabha Acharya from early poems of Sur and the awkward story of their meeting suggests that Sur was an independent poet. The book Sur Sagar (Sur's Ocean) is traditionally attributed to Sur. However, many of the poems in the book seem to be written by later poets in Sur's name. The Sur Sagar in its present form focuses on descriptions of Krishna as a lovable child, written from the gopis' perspective. Sur was a great religious singer.
