Weightthe stone is honest
Every stone carries its own centre. Balance it over the one below or you do not balance it at all — the friction and the falling are real, and neither is forgiving.
The practice
You came down at low tide with nothing to prove.
A cairn is not built. It is negotiated, one stone at a time.
Each stone keeps a single face that will sit and a hundred that won't, and the only way to find it is with your hand and your held breath. Set a stone too eagerly and it answers with the whole tower. Set it well and the shore holds its shape a little longer than you do.
Nothing here moves without you. Step back and the stones wait on the sand. The tide does not.
What the shore asks of you
Three forces, and only one of them is on your side.
The tidetime is a rising line
The water turns on its own clock, not yours. Build while the sand is bare; a surge at the wrong moment reaches under the lowest stone first and asks the rest to follow.
The windsteadiness is the skill
Gusts come off the water and lean on whatever you have raised. A tall cairn is a proud target. A wide base is an old trick, and it is the one that keeps working.
The shelf
Every cairn you raise is kept here.
Hold a stack of three or more steady for a slow count and the shore photographs it — a small dark portrait added to the ledge above the tideline. Leave and come back: they are still standing. This shore remembers who was patient.
