## About Xuanzang and Buddhist Philosophical Works
Xuanzang (玄奘, 602–664 CE) was a celebrated Chinese Buddhist monk, translator, and philosopher of the Tang Dynasty. He is best known for his extensive travels to India in search of Buddhist texts and his prolific translation work upon returning to China. His scholarly contributions shaped the development of East Asian Buddhism, particularly the Yogacara school of thought.
## Uncertain Identification
The title “Yu jia zhen shi pin” (瑜伽真實品 or similar characters) cannot be reliably verified against standard bibliographic sources. While Xuanzang produced numerous translations and commentaries on Buddhist sutras and philosophical treatises—including works on Yogacara doctrine—the exact correspondence of this particular title to a known work remains unclear. Xuanzang’s authenticated major works include translations of the *Yogacarabhumi-sastra* and commentaries on Mahayana texts, but without access to verified sources, the specific content, structure, and arguments of this title cannot be accurately described.
