A very basic concept is that energy flows through places, like water or wind. They call it chi, I would say (holy) spirit. Depending on the position and size of opening (windows & doors) the energy flows fast or slow, changes directions. Which means in some places it slows down into a putrid pond, where a few changes would make that slowing a restful but fresh spot.
Looking at spaces with this perspective actually works.
The same way dirt, messes and clutter will affect the flow negatively.
Colours and symbols differ greatly, but the idea that we are affected by colour and that our surroundings carry meaning, affect us physically and spiritually.
Liturgically it has made me look at the altar differently, processions, the use of windows in the cathedral, thinking on how to mitiage the effect of a gruesome-but-antique pulpit, why I dislike our Maria sculpture (though it’s sound theologically). I have read up on the liturgical year and combined these concepts into how I change things in my own home, permanently and week from week to create ’ritual space’ even if it in practice just ends up as a peaceful breakfast table for morning tea, to watch the garden and contemplate God’s grace.
But I’m into art and architecture so it felt natural.
