The Kośa school (C. Zhushe zong [alt. Chu-she zong]; J. Kusha shū) is a scholastic lineage of East Asian Buddhism based on the study of the Abhidharma-kosa. This lineage was introduced to China by Paramārtha and Xuanzang.
Peter Harvey states:
- Paramārtha (499–569) also introduced the Zhushe (Chu-she), a form of the Sarvāstivāda based on the study of the Abhidharma-kośa. It was then organized by Xuanzang.
One Teacher, Many Traditions states:
- While this school was popular during "the golden age of Buddhism" during the Tang dynasty (681-907), it is small now.
