We are testing ourselves through our craving
153. Through many a birth in samsara have I wandered in vain, seeking the builder of this house (of life). Repeated birth is indeed suffering!
154. O house-builder, you are seen! You will not build this house again. For your rafters are broken and your ridgepole shattered. My mind has reached the Unconditioned; I have attained the destruction of craving.
"Now what is the noble truth of the origination of stress? The craving that makes for further becoming — accompanied by passion & delight, relishing now here & now there — i.e., craving for sensuality, craving for becoming, craving for non-becoming... And what is the noble truth of the cessation of stress? The remainderless fading & cessation, renunciation, relinquishment, release, & letting go of that very craving."
— DN 22
And what is right speech? Abstaining from lying, from divisive speech, from abusive speech, & from idle chatter: This is called right speech.
