In the art of tea, the essence of "harmony and clarity" emerges as the embodiment of natural beauty. From the inception of wabi tea by the founder Murata Jukō, tea practitioners have sought to explore the subtleties of a tranquil life through simplicity and silence. Jukō opposed opulence and advocated for modesty, favoring austere black pottery for its understated elegance and serene beauty. With these humble tea utensils, hosts extend genuine hospitality, finding not only aesthetic pleasure but also nurturing moral refinement.

Embracing the simplicity of Japanese craftsmanship, tea masters often choose utensils in muted, natural tones—like the colors of withered leaves or gentle greens—that harmonize with the atmosphere of quiet contemplation. These earthy hues, defined by their "rustic" quality, capture a raw, unrefined beauty. This aesthetic sensibility, valuing serenity and tranquility, reveals a profound joy in simplicity and fosters a sense of spiritual contentment.

When arranging the tea room, the host seeks to cultivate a sacred, almost otherworldly atmosphere that honors the natural beauty of each element. In the practices and rituals of the tea ceremony, the emphasis is placed on nature over human intervention, celebrating the essence of life in its most authentic and harmonious state. This focus on inner cultivation over material wealth is rooted in Zen philosophy and is a defining characteristic of the tea ceremony.

Japanese tea culture cherishes the principles of "Wa, Kei, Sei, Jaku," along with the "Seven Rules." "Wa" symbolizes harmony with nature; "Kei" embodies the spirit of respect among all beings; "Sei" is about achieving purity of heart and mind, free from distraction, to reach the essence of Zen; "Jaku" signifies a profound tranquility, merging with nature in a timeless stillness.
