Gutei raised his finger whenever he was asked a question about Zen. A boy attendant began to imitate him in this way. When a visitor asked the boy what his master had preached about, the boy raised his finger. Gutei heard about the boy's mischief, seized him and cut off his finger with a knife. As the boy screamed and ran out of the room, Gutei called to him. When the boy turned his head to Gutei, Gutei raised up his own finger. In that instant the boy was enlightened. When Gutei was about to die, he said to the assembled monks,"I received this one-finger Zen from Tenryu. I used it all my life and yet could not exhaust it" and then he passed away.

This is the most profound koan I've contemplated.

The Butte aux Cailles in Paris is a vibrant hub for street art, often described as an open-air museum. Preserved from Haussmann’s urban overhaul, its cobblestone streets and low-rise houses provide a unique canvas for artists. Renowned for its bohemian spirit and history of counterculture, the area attracts both established and emerging street artists. Pioneers like Miss Tic, known for her poetic feminist stencils, and Seth, with his whimsical childlike murals, have left a significant mark, alongside Jef Aérosol, Invader, and The Mosaist. The art ranges from colorful murals and intricate pochoirs to mosaics, collages, and yarn bombing, reflecting diverse techniques and messages—often political, poetic, or ecological. Streets like rue de la Butte aux Cailles, rue des Cinq Diamants, and passage Boiton are hotspots, with works evolving constantly, making each visit unique. Guided tours, such as those by Cultival or My Urban Experience, offer insights into the artists’ stories and continues to draw global attention, cementing Paris, France status as a street art capital.
