Hiri: Moral shame
Hiri is the inward recoil from what falls below one's own standard. The shame that keeps the request for horsemen unspoken is not embarrassment before the court; it is a man who cannot bear to contradict his own mouth. Standing at the river with the caravan loaded and the road ahead, that shame works like a hand on his arm, holding him back from the king's door.
Sacca: Truthfulness
Sacca is a word kept and then walked. Praise of God's hand was cheap to say in a warm hall; out on the road it becomes a bill that comes due. Going without the escort is how he pays it, and the saying turns into something he owns rather than something he performed.
Kamma: Action and its fruit
Kamma is action ripening into a result of its own kind. The hand for good and the wrath against those who forsake run as one law in two directions: turning toward yields one harvest, turning away another, the way a field gives back whatever was put in it. Wrath read this way sounds less like a temper flaring and more like the ground's own answer, which is why he cannot ask for a private exemption from it.
Saraṇa: Refuge
Saraṇa is where a person finally puts their safety. A band of soldiers is a fine shelter as far as it goes, and the old verses reply that people run to mountains and groves and sacred trees when fear arrives, and none of those hold. Choosing the hand over the horsemen is choosing the shelter that does not depend on what the king thinks of him next season.
Saddhā: Confidence
Saddhā is confidence that moves the feet. Seeking is a verb in his sentence, and the long march with the families and the temple silver is what seeking looks like once it stops being talk. Trust of this kind gets tested only by leaving, since a confidence that needs armed riders alongside to stay calm was never leaning on anything.
