Anicca: Impermanence
The same law that took loved ones and left this mourning is the law now turning it into joy. Nothing holds its shape, not the grief either, and the dance rises where the weeping stood because feeling moves like weather across a field. Old and young step in together because none of them owns a fixed state to defend.
Dukkha-nirodha: The ceasing of suffering
Mourning turned to joy is a picture of the ache running all the way out. The comfort here is not a distraction laid over the sorrow but the sorrow itself coming to an end, the way a fever breaks and the body cools. Where the pain stops, gladness is simply what remains.
Muditā: Sympathetic joy
The whole town dances, young men and old and the virgin all in one ring, each one's gladness feeding the next. This is the delight that widens when it is shared, a room where one person's laugh sets everyone else off. Grief had isolated them, and joy gathers them back into one circle.
Pīti: Rapture
The body cannot hold this and stays still, so it dances. Joy that reaches full strength spills into the limbs, the way good news lifts you onto your feet before you decide to move. The turning from sorrow lands in the body first, as gladness the feet have to spend.
Upekkhā: Equanimity
He turns their mourning; the change comes from outside their grip, and their part is to receive it. Steadiness like this does not clutch the new joy any harder than it clutched the old grief, knowing both arrive and both pass. Held this way, the dance can be full without the fear of when it ends.
