Ok, the dog, is tenth of the twenty, following Muluk the water: after the overflow, loyalty and company. The Maya dog has a particular role — it carries the dead across the underworld river as the soul's guide; it's also the animal at home who knows everyone. So Ok is about recognising: your own people, the way home, what's yours to keep.
So Ok's mechanism is loyalty and guidance: you stay longer than most, and people with you have a sense of direction. Its power is dependability — when you're there, people settle; its difficulty is staying too long — the relationship that should have ended, the person no longer worth it, and you're still keeping watch.
Where you'll recognise it: loyal to friends and partners, wounded by betrayal more than most, a strong need to belong, often the one in a group who brings people back, and not much attention on your own needs. Running well, you're the best companion and guide: giving people a home, a direction, one person who won't leave. Stuck, you keep the wrong watch or keep it until there's nothing left of you — loyalty becomes inability to leave, others' paths taken for your own. In the sequence Ok is followed by Chuwen, the monkey: once loyalty stands firm, play and making. Your next step isn't holding tighter. It's allowing yourself a little pleasure that isn't dutiful.
