Ditrich/Satipaṭṭhānasutta, 1. Introducing the Four Foundations of Mindfulness (cattāro satipaṭṭhānā)

Chapter 1 introduces the main topic, with a special focus on making precise what mindfulness (sati) is, discussing its foundational role in Buddhist meditation and within the entire Buddhist doctrinal framework. Also explored are basic concepts related to mindfulness, such as attention, wise attention, clear comprehension and right mindfulness, clarifying linkages and differences. Then the four main areas of mindfulness (satipaṭṭhānas), are presented, namely, (1) the body, (2) feelings, (3) the mind and (4) mental phenomena, along with how they interrelate and are situated in either calm or insight meditation. Subsequent chapters take up each of these in turn.
