The calligraphy inscription of Rikyū's famous portrait by Hasegawa Tōhaku was written by Sōen at the request of Sen Dōan. Sōen passed away in 1611 at the age of 83. His grave is at Sangen-in. Shun'oku Sogen was a Zen monk and a founder of several temples during the late 16th century in Japan. As a spiritual leader, he did not create works of art for commercial purposes, so it is not appropriate to talk about his "most expensive work." However, Shun'oku Sogen is renowned for his calligraphy and is considered one of the greatest Zen calligraphers in Japan's history. Some of his calligraphy works are highly valued and considered national treasures, but they are not sold in the market. Instead, they are preserved and exhibited in museums and temples for their historical and cultural significance. Shun'oku Sogen is known for his contributions to the development and transmission of the tea ceremony in Japan, particularly the incorporation of Zen principles into the ceremony. One of his famous offerings is the "Jukoan Tea Ceremony," which emphasizes the Zen concept of "ichi-go ichi-e," meaning "one time, one meeting." This concept emphasizes the importance of being fully present in the moment and cherishing each encounter as a once-in-a-lifetime experience. The Jukoan Tea Ceremony is still practiced today and is considered a valuable contribution to Japanese tea culture.
