[572] How is it a factor of awakening (bojjhaṅga) [in the sense]: "If the equanimity factor of awakening is thus present in me"? So far as cessation (nirodha) becomes manifest, so far it is a factor of awakening [in the sense]: "If the equanimity factor of awakening is thus present in me." Just as, when an oil lamp is burning, as far as the flame extends, so far extends the radiance, and as far as the radiance extends, so far extends the flame — even so, so far as cessation becomes manifest, so far it is a factor of awakening [in the sense]: "If the equanimity factor of awakening is thus present in me."¹
How is it a factor of awakening [in the sense]: "It is measureless for me"²? Defilements (kilesa) are measurable, as are all obsessions (pariyuṭṭhāna) and the volitional formations that lead to renewed existence; cessation is measureless, in the sense of being unconditioned (asaṅkhata). So far as cessation becomes manifest, so far it is a factor of awakening [in the sense]: "It is measureless for me."
How is it a factor of awakening [in the sense]: "It is well undertaken by me"? Defilements are uneven, as are all obsessions and the volitional formations that lead to renewed existence; cessation is an even state, in the sense of being peaceful, in the sense of being sublime. So far as cessation becomes manifest, so far it is a factor of awakening [in the sense]: "It is well undertaken by me."
How is it that, while moving about, I clearly know it as it stands: "It stands," and if it falls away, I clearly know: "It falls away for me owing to this condition"? In how many ways does the equanimity factor of awakening stand? In how many ways does the equanimity factor of awakening fall away? In eight ways the equanimity factor of awakening stands; in eight ways the equanimity factor of awakening falls away.
