Ekadhammasutta

Suttapiṭaka · Saṁyuttanikāya · Mahāvaggasaṁyutta · Vol. 19 · Section 455

[455] Bhikkhus, I do not see even one other thing which, when thus developed and cultivated, leads to the abandoning of things conducive to the fetters (saṃyojaniyā dhammā) as do these seven factors of awakening (bojjhaṅga). What seven? The awakening factor of mindfulness … the awakening factor of equanimity.
