bhaktavataram isam tam
advaitam—known as Advaita; harina—with Lord Hari; advaitat—from being nondifferent; acaryam—known as Acarya; bhakti-samsanat—from the propagation of devotional service to Sri Krsna; bhakta-avataram—the incarnation as a devotee; isam—to the Supreme Lord; tam—to Him; advaita-acaryam—to Advaita Acarya; asraye—I surrender.
Because He is nondifferent from Hari, the Supreme Lord, He is called Advaita, and because He propagates the cult of devotion, He is called Acarya. He is the Lord and the incarnation of the Lord's devotee. Therefore I take shelter of Him.
