This is a calligraphy piece by Jiko Tsusho, the 55th Abbot of the Obaku school of Zen Buddhism. The inscription is from a Zen phrase, "Sanka hiraiteni nishiki ni nitari" (山花開似錦). The meaning expresses the beauty of mountain flowers blooming in a variety of colors, resembling a brocade. This phrase is based on Buddhist teachings, particularly Zen philosophy. It is a passage from a Zen dialogue originating in the "Hekiganroku" (碧巌録), a book from the Tang Dynasty. A monk asked a renowned monk, "What is the unchanging, eternal truth that remains even after the body perishes?" The renowned monk replied, "Mountain flowers bloom like brocade, and the water in the valley is as clear as indigo (山花開似錦、澗水湛如藍)." This story teaches that the everyday scenery itself is the truth. Please note that this work is over 50 years old, and some staining is present.
