Yamaka is a term used in the context of Buddhism, particularly in the Pali Canon. It refers to a type of dialogue or discussion that explores the nature of reality and the concept of duality. Yamaka often involves a series of questions and answers that help clarify complex philosophical ideas. In the Yamaka Sutta, a key text, the Buddha engages in a methodical examination of various concepts, such as existence and non-existence. This approach encourages practitioners to reflect deeply on their understanding of the world and to recognize the limitations of conventional thinking.
