I stumbled across the Seven Elements of Shibusa/Shibui last week while researching the term, Shibusa. I vaguely remembered reading about it years ago when I was doing plenty of research on Japanese gardens and Japanese design aesthetic.
The seven elements are simplicity, implicity, modesty, silence, naturalness, everydayness, and imperfection.
During my Google search I came across this bit of writing and loved it:
Simplicity An aesthetic experience
producing quietude. Implicity Depth of feeling through spare surface
design manifesting the invisible core Modesty exalts excellence via understatement
and silence concerning oneself Modesty Silence A sanctuary of silence is non-dualism...the resolution
of opposites, is intuition coupled with beauty and faith Naturalness Roughness, irregular asymmetry wherein the center
lies beyond all particular things in infinity Everydayness A framework for an artist's oeuvre
to be a unit not a process Imperfection Beauty with inner implications...beauty
that makes an artist of the viewer.
Shibusa, or Shibui, is different from Wabi-Sabi. But I am not going to explain that right now. You can look it up.
