SN46.49 — The Discourse on the Internal Factor

Disciples, considering the internal factor, I do not see any other single factor that is so conducive to the arising of the seven factors of enlightenment as wise attention. For a disciple who is endowed with wise attention, it is to be expected that he will develop and cultivate the seven factors of enlightenment.

And how does a disciple who is endowed with wise attention develop and cultivate the seven factors of enlightenment? Here a disciple develops the enlightenment factor of mindfulness, which is based on seclusion, dispassion, and cessation, and matures in relinquishment. He develops the enlightenment factor of equanimity, which is based on seclusion, dispassion, and cessation, and matures in relinquishment.

In this way a disciple who is endowed with wise attention develops and cultivates the seven factors of enlightenment.
