During this talk, Peter explained how these seven factors, led by mindfulness, function.  Initially, in their undeveloped, weakest form, they apply a counter to the action of the five hindrances.  As the hindrances are set aside and the function of the mind becomes clarified, coherent and energized, the seven factors are matured in their function: “During the first stages of practice, they function to ward of the demons; as that is accomplished, they function to feed the angels!”  The angels are mental clarity, compassion, generosity, kindness, etc.
