About the Abhidhammattha Sangaha:
“This work is ascribed to Acariya Anuruddha, a Buddhist savant about whom so little is known that even his country of origin and the exact century in which he lived remain in question. Nevertheless, despite the personal obscurity that surrounds the author, his little manual has become one of the most important and influential textbooks of Theravada Buddhism. In nine short chapters occupying about fifty pages in print, the author provides a masterly summary of that abstruse body of Buddhist doctrine called the Abhidhamma. Such is his skill in capturing the essentials of that system, and in arranging them in a format suitable for easy comprehension, that his work has become the standard primer for Abhidhamma studies throughout the Theravada Buddhist countries of South and Southeast Asia. In these countries, particularly in Burma where the study of Abhidhamma is pursued most assiduously, the Abhidhammattha Sangaha is regarded as the indispensable key to unlock this great treasure-store of Buddhist wisdom.”

“The Abhidhammattha Sangaha, the authorship of which is attributed to the Venerable Anuruddha Thera, an Indian monk of Kanieevaram (Kancipura), gives an epitome of the entire Abhidhamma Pitaka. It is still the most fitting introduction to Abhidhamma. By mastering this book, a general knowledge of Abhidhamma may easily be acquired.”
