Tattvacintamani

Tattvacintamani is a seminal Buddhist text that consists of a combination of dialogues and discussions between King Prajvankara and his minister, Nagabodhi. The text is a treatise on Mahayana Buddhist philosophy, particularly on the principles of yogacara (mind-only) and the nature of reality. It is believed to have been composed in the 9th or 10th century.

The title Tattvacintamani is often translated as "Earth-touching jewel" or "Pearl on which the eye rests". The text itself is a comprehensive guide to the principles of Mahayana Buddhism, covering topics such as the nature of the mind, the relationship between subject and object, and the concept of emptiness (shunyata).

Throughout the Tattvacintamani, the king and his minister engage in a series of intellectual and philosophical discussions, debating the finer points of Buddhist doctrine and practice. The text presents the view of the Indian Mahayana philosopher, Sthiramati, who is often referred to as the chief expositor of the Yogacara school.

Tattvacintamani is an important work in the development of Mahayana philosophy, and has had a significant influence on subsequent Buddhist thought and practice. Despite its historical importance, the text remains relatively unknown outside of specialized Buddhist studies circles.
