Yamaka (The Couple of Investigative Points / The Book of Pairs) is the 6th Book of the Abhidhamma Piṭaka. There are all 10 Chapters of Yamaka.
Citta Yamaka is the 8th Chapter of Yamaka. It is translated as “The Couple of Investigative Points on Consciousness” or “The Pairs on Consciousness”.
The Pāḷi Canon falls into three general categories, called piṭaka (basket) in Pāḷi. Because of this, the canon is traditionally known as the Tipiṭaka (three baskets).
The three piṭakas are as follows: 1. Vinaya Piṭaka, dealing with rules for monks and nuns 2. Sutta Piṭaka, discourses, mostly ascribed to the Buddha, but some to disciples 3. Abhidhamma Piṭaka, variously described as philosophy, psychology, metaphysics etc.
The Abhidhamma Piṭaka is the last of the three piṭakas, constituting the Pāḷi Canon, the scriptures of Theravāda Buddhism. It presents a more formal, abstract, systematic form of teaching than the others.
The Abhidhamma Piṭaka consists of seven books. 1. Dhammasaṅgaṇī (Classification of Dhamma) 2. Vibhaṅga (Analysis or Division) 3. Dhātukathā (Discussion of Elements) 4. Puggalapaññatti (Descriptions of Individuals) 5. Kathāvatthu (Points of Controversy) 6. Yamaka (The Book of Pair) 7. Paṭṭhāna (The Book of Causal Relation)
