The author presents a selection of papers written over the last twenty or so years, spanning the period from early research into the then nearly unknown Madhyamika writer Bhavaviveka or Bhavya, amongst Tibetan refugees in India, up to the recent past where there interests have, perhaps, somewhat broadened to include comparative religion. The author has moe or less left the essays in their original form and has introduced some consistency in the citing of the names of Japanese scholars in order to aid the English speaking reader unfamiliar with Japanese.
