The Pali fragment contains the descriptions of buddhist meditational practices, written originally on palm leaves. The Satipatthana Sutta is one of the most important early buddhist sacred writings.
The word satipatthana is the name for an approach to meditation aimed at establishing sati, or mindfulness.
The term sati is related to the verb sarati, to remember or to keep in mind. It is sometimes translated as non-reactive awareness, free from agendas, simply present with whatever arises, but the formula for satipatthana doesn’t support that translation. Non-reactive awareness is actually an aspect of equanimity, a quality fostered in the course of satipatthana.
The activity of satipatthana, however, definitely has a motivating agenda: the desire for Awakening, which is classed not as a cause of suffering, but as part of the path to its ending.
The role of mindfulness is to keep the mind properly grounded in the present moment in a way that will keep it on the path.
To make an analogy, Awakening is like a mountain on the horizon, the destination to which you are driving a car. Mindfulness is what remembers to keep attention focused on the road to the mountain, rather than letting it stay focused on glimpses of the mountain or get distracted by other paths leading away from the road.
