Nibarkacyara

NIMBARKACARYA was the principal acarya in the Kumara sampradaya, one of the four main lines of Vaisnava teachers and disciples. His Vedanta-sutra commentary -- Parijata-saurabha- bhasya -- establishes the doctrine known as Dvaitadvaita-vada. He preached Krsna consciousness about 300 years before the advent of Sri Caitanya Mahaprabhu.
