The abstract introduces three Buddhist texts: two from the Theravādin Pali canon—the Anatta-lakkhaṇa Sutta and a portion of the Mahānidāna Sutta—and one postcanonical text, the Milindapañha. Although these works contain philosophically relevant points and arguments, they are not systematic philosophical texts. To properly grasp their nuances and implications, one must understand their context of thought and practice.
Pojo Chinul (1158–1210), a pivotal figure in Korean Zen Buddhism, developed a philosophy of mind that underpins his method of huatou (critical phrase) meditation, a form of encounter dialogue practice. His thought evolved through three distinct stages, as traced by examining his account of mind.
