Nimbarka

Nimbarka, also known as Nimbarkacharya, Nimbaditya or Niyamananda, was a Hindu philosopher, theologian and the chief proponent of the theology of Dvaitādvaita (dvaita–advaita) or dualistic–non-dualistic sometimes known as Svābhāvika bhedābheda. He played a major role in spreading the worship of the divine couple Radha and Krishna, and founded the Nimbarka Sampradaya.

Nimbarka is believed to have lived around the 12th century, but this dating has been questioned, suggesting that he lived somewhat earlier than Shankaracharya, in the 6th or 7th century CE. Born in Southern India in a Telugu Brahmin family, he spent most of his life in Mathura, Uttar Pradesh. He is sometimes identified with another philosopher named Bhaskara, but this is considered to be a misconception due to the differences between the spiritual views of the two saints.
