The cold mornings and evenings and the earlier sunsets each day make you feel the arrival of winter.
Originally, wabi-sabi is said to have referred to negative emotion such as loneliness and poverty, but it was established as a concept that enhances aesthetic value in medieval Japan, where unique cultures such as the tea ceremony and Noh theater had developed.
In Japan's four seasons, this time from late autumn to winter is the season when you can feel wabi-sabi even more. It is the time when plants wither and decay, and all life in nature comes to an end, giving a strong sense of the impermanence of all things. Since ancient times, Japanese people have tried to sense these insignificant changes when something small comes to an end. And while superimposing their own lives on the changes in the natural world and lamenting the transience of life, they have expressed this spirit in waka poetry and ikebana, which have been sublimated into art. This is a sensibility unique to the Japanese, and is the spirit of wabi-sabi.
There is a japanese word "kinomotiyou" that means "it's all in your mindset." Wabi-sabi may be close to that nuance. There are many things around us, especially in the natural world, that we cannot control. Accepting things that wither and decay, and trying to find beauty in them. This kind of spirit, which can be seen as giving up something in a positive way, can sometimes give us peace of mind.
