I am offering for sale a genuine calligraphy shikishi (square card) by the late Yūya Sakai, a great ascetic monk of Mount Hiei, who twice completed the arduous Sennichi Kaihōgyō (thousand-day training) practice. If you are interested, please consider acquiring this piece. Please examine the images carefully before purchasing. We kindly request that those who are overly concerned with minute details, or who are seeking a brand-new, perfect item, refrain from purchasing.
