Yadunandana dasa or Thakura was a Vaidya by caste and a disciple of Hemalata, the daughter of Shrinivasa Acharya.
His Shripata was at Malihati village (or Meleti) to the north of Katoa. He wrote the book which contains a biography of Shrinivasa Acharya. In his book Karnananda, Shri Yadunandana dasa mentions the name of his guru at the end of every chapter and respectfully glorifies her: “Hemalata, the daughter of Shrinivasa Acharya prabhu, is just like a creeper of divine love and is a beautiful creation of the Supreme Lord. I, Yadunandana dasa, take pleasure in writing the book Karnananda, keeping her lotus feet fixed within my heart.” Upon hearing this book Hemalata Devi was deeply impressed and named it Karnananda.
