Dukkha: Suffering
Dukkha is the ache built into birth, aging, and every parting. Jabez wears it as a name, given because his mother bore him in sorrow, so he hears his own pain spoken back at him by everyone who greets him in the street. His prayer rises from a wound handed to him before he was old enough to act, which is where most people begin.
Adhiṭṭhāna: Firm determination
Adhiṭṭhāna is a mind set on a course and held there. Jabez speaks over the name he was given, saying in one breath what he wants his life to hold and what he wants it to keep out. Loose wishes drift and dissolve; a resolve stated this plainly gives the mind an outline to grow into, and his is answered.
Appamaññā: The immeasurable heart
Appamaññā names the four boundless states, trained by sending goodwill toward one direction, then the next, until no direction is left out. A border can be the fence line of a field, and it can be the point where a person's care runs out; Jabez asks for the second one to move outward. Handed a small, sore identity at birth, he wants room, and the room that lasts is counted in how many people he can hold.
Kamma: Action and its fruit
Kamma is the working link between intention, deed, and what comes back. "Keep me from evil" asks for help at the one place harm can still be stopped, the moment before the hand moves, since afterward there is only the fruit. He received pain without choosing it; whether he passes pain on is a separate question, and that one is his to answer.
Avihiṃsā: Harmlessness
Avihiṃsā is the intention to injure no one, the third strand of right intention. The whole prayer bends toward its final clause: he asks for blessing, land, and protection so that the pain in his name stops with him. A man could want a wider border in order to push others off it; this one asks for the width and then binds himself to leave every person inside it unhurt.
