In the days when "paper" had not existed yet, our ancestors left what I wanted to convey to future generations and my intention and philosophy / thought on the stone.
There is an age where "intention" dwells in the stone and it was believed for a long time, even now it is used in various places including the shrine temples and temples.
Paper was invented, and there was no longer to carve various thoughts on the stone board.
"Carve on stone = Set in Stone"
In the UK, it seems that you use Set in Stone routinely to mean "not changing easily, keeping intention."
「Carve ～ Kizam ～」
