Padmanabha (or Padmanabha Tirtha)
Padmanabha Tirtha (c. A.D. 1199–1278) appeared in Uttara-Karnataka. He was a renowned and distinguished scholar, but his proficiency in fourteen branches of learning was silenced in fourteen seconds by Madhvacharya when they met in A.D. 1265. Consequently, Padmanabha took initiation and sannyasa from Madhvacharya and soon became one of his most trusted disciples. Padmanabha Tirtha left this world in A.D. 1324 at Nava-vrindavana, on the sacred river Tungabhadra.
