Venerable KL Dhammajoti, PhD., is presently Endowed Professor of Buddhist Studies at the Centre of Buddhist Studies, the University of Hong Kong. Prior to joining the University of Hong Kong, he was Professor and Head of Department of Buddhist Literary Sources of the Postgraduate Institute of Pali and Buddhist Studies, University of Kelaniya, Sri Lanka. For the past many years, he has been specializing in Abhidharma studies and early Indian Yogācāra.

The period of Abhidharma Buddhism contributed most significantly to the development in Buddhist thought in the history of Indian Buddhism. An understanding of the active doctrinal development in this period is therefore indispensable for gaining a proper perspective of the development in Buddhist thought in India as a whole.

This book deals with the Buddhist theories of perception of the Abhidharma schools, particularly the Vaibhāṣika and the Sautrāntika-Dārṣṭāntika. It offers a wealth of information from the Sanskrit and Chinese sources, of which those from the Abhidharma-mahāvibhāṣā and *Nyāyānusāra are especially valuable, being available only in Classical Chinese translation.
