Dukkha: Suffering
Dukkha is the ache of things not coming out even. A man works a full day and an ox pulls a full load, and at sundown nothing comes into either hand; wanting and not getting is its plainest form. The empty palm teaches this better than any disaster, since it shows how ordinary the ache is, spread thin across every working day.
Vera: Enmity
Vera is the hostility that keeps answering itself. Set every man against his neighbor and the quarrels multiply into a field of them, each side certain it is only repaying what it received. Hatred never settles by hatred; the feud between two houses on the same street stays lit because both keep feeding it.
Khema: Safety
Khema is being out of danger, the safe place. Going out and coming in is the whole shape of a working life, the gate at dawn and the gate at dusk, and when neither is safe the fear never lets up. With an adversary on the road, that fear does not stay outside the door; it comes home and sits down with the family.
Paṭicca-samuppāda: Dependent origination
Things arise leaning on other things. Empty wages, an unsafe road, and a neighbor turned adversary form one knot: no one plants when the crop will be taken, and no one trusts the man who took it. Pull any strand and the others move, which is why the promised turn has to touch all three at once.
Anicca: Impermanence
Everything put together comes apart, including the bad years. "Before those days" already places the speaker on the far side of the ruin, looking back at a stretch of time that felt permanent while it lasted. The lean season had no more staying power than the good one coming; both run on conditions, and conditions turn.
Mettā: Loving-kindness
Mettā is goodwill that leaves no one out. Where each man stood set against his neighbor, it begins by wishing that same neighbor well, including the one who owes you and the one you owe. The animal that went unpaid belongs inside the wish too, since the old formula covers every breathing thing, the ox in the yard as much as the man in the house.
