This book investigates the precise definition and soteriological function of 'sati' (mindfulness) within early Buddhist philosophy and practice. Tse-fu Kuan, drawing upon his doctoral research at the University of Oxford, utilizes a rigorous comparative methodology to analyze primary source texts across Pali, Chinese, and Sanskrit traditions. By integrating these classical textual findings with contemporary psychological frameworks, the author constructs a comprehensive model of how mindfulness operates as a mechanism for cognitive and emotional transformation.

Scholars and practitioners recognize this work as a significant contribution to the academic study of early Buddhist meditation techniques. Readers frequently note the high level of academic density and the meticulous nature of the textual comparisons provided by the author.
