[528] "And what, bhikkhus, is the nutriment (āhāra) for the arising of the unarisen awakening factor of mindfulness (sati-sambojjhaṅga), and for the development and fulfillment of the arisen awakening factor of mindfulness? There are, bhikkhus, dhammas that serve as a basis for the awakening factor of mindfulness: frequently applying wise attention (yoniso manasikāra) to them — this is the nutriment for the arising of the unarisen awakening factor of mindfulness, and for the development and fulfillment of the arisen awakening factor of mindfulness."
