Zen enso - circular brushstroke embodying enlightenment and void, painted with traditional sumi-e ink on washi paper. Single decisive stroke capturing imperfection and completion simultaneously. The circle remains deliberately incomplete, symbolizing the beauty of impermanence and non-attachment. Negative space dominates the composition, expressing the concept of 'ma' - meaningful emptiness. Ink texture varies from rich black to delicate gray wisps where brush hairs separate. Background features subtle tea stains and natural fiber patterns in warm beige tones. The composition evokes yugen - profound mysterious beauty beyond words. Masterful balance between presence and absence, form and emptiness. Minimalist aesthetic with philosophical depth, inviting contemplative gaze. High-quality fine art photography capturing authentic Zen artistic expression. <lora:风格化-超现实:0.6> <lora:Niji V2B:0.5> <lora:黑色幻想_1.0:0.1> <lora:Anime realistic V1:0.7> <lora:flux_dev:1>
