During his six years of seclusion, he meditated and studied Buddhism's vast library of scriptures and penned nine works, including Comparative Religion and Orthodox Chinese Buddhism, thus laying the foundation for his later propagation of Buddhism.
在 6 年閉關期間，他除了打坐，便是埋首浩瀚佛教文獻，從佛教初期經典、禪宗與佛教八大宗派文獻到佛教歷史傳記，逐冊研讀，據而完成《比較宗教學》、《戒律學綱要》、《正信的佛教》等 9 部著作，奠定日後弘法基石。
