Saṃvega: Urgency stirred by shock
Saṃvega is the jolt that turns a life around. A changed face in the middle of a drinking party is that jolt landing: the hand writes on the plaster, the wine goes flat, and the cups looted from a temple stop looking like ornaments. Terror like this is worth keeping a moment longer, since it is the one thing in the hall pointing him somewhere other than back to his lords.
Uddhacca-kukkucca: Restlessness and worry
Uddhacca-kukkucca is agitation braided with remorse. Asking him to stop letting his thoughts trouble him is asking for still water: a pond whipped by wind shows no face at all, and he needs to see something. His worry has a cause behind it, so soothing words will settle the surface and leave the bottom stirred.
Upekkhā: Evenness that the weather does not move
Upekkhā is steadiness under pressure. She walks into an uproar of knocking knees and shouting nobles with her voice level, the way one calm person in a frightened room brings the volume down. Composure like hers comes from having watched a throne before this one shake and hold, so the panic finds nothing in her to catch on.
Maraṇassati: Keeping death in view
Maraṇassati is holding your own death in mind. "O king, live forever" is court manners offered to a man with one night left, the way we still tell someone to take care as they head out the door. Said honestly the sentence runs the other way, and hearing it early is the whole use of it.
Kalyāṇamitta: The good friend
Kalyāṇamitta is the companion who moves you toward what is true. Nobody else in that hall can help him: the enchanters have already stared at the wall and gone quiet, and his lords are half the reason he is drinking. She arrives with one useful thing, a name, which is most of what good friendship ever amounts to, someone who knows where to send you.
