As someone on the ASD spectrum I know myself how important routine is for me. I believe routine and peace together provide a harmonic balance that help maintain each other for a peaceful life with a stable reassuring routine where risks and anxiety are minimised.
I came up with a brief diagram of some of the things that help to bring each of these into our lives (I came up with the diagram with myself in mind but if it helps anyone else then that's great).
I believe peace and routine need each other, if there is a breakdown with one then the other is at risk of breakdown. I need a routine to feel reassured and peaceful, and I need to feel peaceful to go through my routine smoothly.
