Zen Bull 

This Zen painting by Kogan Gengei, a prominent Japanese Zen monk and artist, depicts a bull in a bold and expressive style. The black ink, applied with a brush, creates a dynamic and energetic image of the bull's form, emphasizing its powerful presence. The simplified strokes and minimal details reflect the Zen philosophy of simplicity and directness. This artwork exemplifies the concept of "sumi-e," a traditional Japanese ink painting style, and demonstrates the artist's mastery of brushwork and ink control.
