The Essence of Scholasticism can be used as a meditation guide to attain arhatship. It is the core text of the Gandharan culture’s westernmost part. It was probably composed in the first century BCE. It was discussed and expanded upon in many sastras, the most well-known being the Abhidharmakosabhasya from the fifth century. The basic treatises of non-Vaibhasika Sarvastivadins are the Essence and Astagrantha. The sautrantikas are the Gandharan Cultural Area’s main treatises.
