The "Linked Discourses on Feeling" explores the nature of felt experiences—pleasant, painful, and neutral—as a fundamental aspect of experience. These teachings examine how feelings arise, their role in shaping perception, and the underlying tendencies that lead to attachment or aversion. By understanding the conditioned nature of feeling and its cessation, these discourses offer insight into the path to liberation and the ending of suffering.
Vedanāsaṁyutta - Linked Discourses on Feelings
The Buddha explains the difference between an uninstructed ordinary person and a learned noble disciple in how they experience pleasant, painful, and neither-painful-nor-pleasant feelings.
