Kalyāṇamitta: The admirable friend
An admirable friend is one whose company carries you along the path. Being called, rather than climbing on your own steam, puts the first move outside yourself: someone spoke, and the walking started from there. For readers scattered as exiles with their old standing stripped away, an address from outside was the one possession persecution could not confiscate.
Khanti: Patient endurance
Patience is the capacity to stay steady and kind under what comes. Suffering "a little while" asks you to stand inside the pain until it finishes, with the lion of the preceding lines still prowling and no promise it will be called off. Enduring is work, holding your ground while the mind gives up its demand that this stop now.
Anicca: Impermanence
Whatever is put together comes apart. "A little while" measures the suffering itself: assembled out of conditions, so it will come unassembled, the way any storm does. Believing otherwise lays a second suffering over the first, the dread that this is the permanent shape of your life, and that added weight is the one you can set down today.
Bhāvanā: Cultivation
Cultivation brings something to fullness through repeated work. The word behind "perfect" is the one used for mending nets, ordinary labor to a fisherman: torn cords knotted back together until the net holds fish again. Suffering stands earlier in the sentence and the mending after it, so the tear is exactly where the hands go.
Bala: The strengths
Confidence, energy, mindfulness, collectedness, and wisdom count as strengths once nothing can knock them over. Strengthening works like a muscle under load, where the weight that hurts is the same weight that builds. The promise therefore arrives on the far side of the suffering, since pressure is what made these five able to carry anything.
Akuppā cetovimutti: Unshakable freedom of mind
Release that no condition can disturb. "Establish" and "settle" point at ground beneath the feet, a state in which circumstances have lost their leverage on you, and it arrives as a result rather than a resolution. A solid rock stands through wind from every side, and praise and persecution are both only wind.
