We examine the first part of Madhupiṇḍika Sutta, The sweet essence (MN 18), where Mahā Kaccāna unpacks a brief teaching by the Buddha on how we construct our dukkha. We begin with the six sense fields and the vedanā that arises from them, and then construct a world though obsessive thinking (papañca), to the point where we find ourselves living in a world of concepts about our experience, rather than the experience itself.
