Entry Into the Inconceivable is an introduction to the philosophy of the Hua-yen school of Buddhism, one of the cornerstones of East Asian Buddhist thought. Cleary presents a survey of the unique Buddhist scripture on which the Hua-yen teaching is based and a brief history of its introduction into China. He also presents a succinct analysis of the essential metaphysics of Hua-yen Buddhism as it developed during China's golden age and full translations of four basic texts by seminal thinkers of the school.
