Hakuin 

Enji Torei, a prominent Japanese Zen monk and artist, was known for his ink paintings, or *sumi-e*. This artwork, titled "Hakuin," embodies the Zen philosophy of finding enlightenment through simplicity. The calligraphy on the scroll likely contains a poem or Zen koan, a riddle designed to spark spiritual insight. The abstract strokes of the brush create a powerful image, with the large, sweeping lines suggesting a sense of movement and energy. This artwork showcases Torei's mastery of brushwork, creating an evocative and introspective piece, characteristic of Zen art.
