Summary: The T‘ien-t’ai school, based on the Saddharma Pundarika, differs in its approach to Mahayana Buddhism philosophy by focusing on the Yogacara-bhimi. Important texts such as Yoga-vibhāga and Dasa-bhimika Sastra in ten stages were influential in this sect, with Chinese translations. The Madhyanta Vibhaga presents Yogacarin interpretation of Madhyamika theory. Alambana Pratyaya Sastra deals with sense impressions causality by Dignaga, translated twice in Chinese. Pramāṇa Samuccaya by Dignaga on Buddhist philosophy and logic is lost. Vidyamatra Siddhi by Vasubandhu, based on Lankavatara Sūtra, simplified idealism with three Chinese translations. Chinese compendiums like Fo-tsu-t‘ung-chi compile cosmological references from Mahayana and Hinayana texts in the Chinese Canon. The text discusses cosmic dynamics like time, months, seasons, and the material realm, including causal factors affecting sentient beings. The classification of mental and physical elements in sentient beings and the Buddha Kṣetra doctrine in Mahayana Buddhism highlight rebirth for spiritual progress in Buddha lands.
