rendered in Chinese ink brush calligraphy style. Letterforms painted with a fully loaded sumi ink brush — deep black ink, visible bristle marks along stroke edges, wet ink pooling at stroke starts, feathered dry-brush trailing ends. Authentic ink density variation: thick rich black cores fading to grey at thin passages. Rice paper texture visible behind. Traditional Chinese calligraphy energy — each stroke confident, intentional, irreversible. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the sumi ink medium, the bristle and ink-density behavior and the rice-paper ground. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as deep black sumi brush strokes with visible bristle marks, wet ink pooling at stroke starts and feathered dry-brush trails on rice paper. COLOR PRIORITY: keep the font's own colors if specified; otherwise rich black ink fading to grey at thin passages. Create a finished, contemplative calligraphy artwork featuring exactly the four characters “禅無心慈”, arranged top to bottom in a single vertical column at the center. Give the characters generous breathing room and clear separation, with “禅” leading and “慈” concluding the composition. Let the column occupy most of the canvas height while preserving broad, quiet margins. Set it on warm ivory xuan paper, with fine visible fibers and subtle natural variation in tone. Behind the characters, add a restrained ink-wash landscape: a few distant mist-softened mountain contours and a barely suggested river, rendered in pale grey so the paper remains luminous and the lettering stays dominant. Keep the landscape sparse and low in contrast, dissolving into untouched paper near the edges. Place one small vermilion seal impression near the lower right margin as a modest accent, separate from the four requested characters and not resembling additional readable text. The overall composition should feel balanced, meditative, and intentional, with ample negative space and no modern objects, borders, or decorative clutter.
