[540] And what, bhikkhus, is not nourishment for the arising of the unarisen mindfulness factor of awakening (satisambojjhaṅga), or for the development and fulfillment of the arisen mindfulness factor of awakening? There are, bhikkhus, things that serve as a basis for the mindfulness factor of awakening: frequently not giving attention (amanasikāra) to them — this is not nourishment for the arising of the unarisen mindfulness factor of awakening, or for the development and fulfillment of the arisen mindfulness factor of awakening.
