In this meditation, we are reminded that we direct attention where we choose because it is skillful. The Satipatthana Sutta is the Buddha’s core teaching on the Four Foundations of Mindfulness: Mindfulness of the body in the body; Mindfulness of feeling tones in feeling tones (whether something is pleasant, unpleasant, or neutral); Mindfulness of the mind in the mind; Mindfulness of objects of the mind.
