Kalyāṇamitta: The Good Friend
The admirable companion who steadies another's undertaking. An old king, forbidden to raise the house himself, hands his son the plans, the gathered cedar and gold, and words to stand on. Support of this kind arrives as materials and as nerve together, and the charge keeps working long after the voice that gave it falls silent.
Saddhā: Confidence
Trusting confidence, the faculty that gives an undertaking its footing. "Don't be afraid" rests on what follows it, "my God is with you," so the steadiness is borrowed from something already trusted rather than manufactured on the spot. Solomon has laid no stone yet, and this is what lets a person put weight on a plank before seeing it hold.
Viriya: Energy
Sustained exertion, one of the five faculties. "Be strong and courageous" lands on two plain words, "do it," and the rest of the charge exists to serve those two. Courage of this kind shows up as arms that keep hauling stone through years of quarrying and measuring, rather than as a feeling worked up in advance.
Adhiṭṭhāna: Resolve
Firm determination to carry a thing to its end. The promise runs "until all the work is finished," so the finishing point is set into the charge on the first day instead of being discovered somewhere along the way. Resolve carries a builder across the long middle stretch, when the trench is dug and the site still looks like a hole in the ground.
Appamāda: Diligence
Heedfulness, care kept unbroken across a long task. These are close to a dying man's last words to the one taking over, and the Buddha's own final charge had the same shape: everything falls apart, so carry on with care. A charge like that has to be taken up again each morning, or it thins into the memory of a fine speech while the cedar sits stacked in the yard.
