Soft golden morning light with gentle rim lighting. Misty mountains and ancient Buddhist temple stupas fading into the background, creating depth and a peaceful spiritual atmosphere. Subtle haze, warm earth tones, cinematic lighting, natural stone textures, shallow depth of field. A tranquil lotus flower near still reflective water in the foreground.

+Generate a short, original Buddhist-style quote about mindfulness, impermanence, inner peace, or awareness. The quote must be calm, timeless, and simple (no modern language, no slang). Keep it under 18 words.
+
+Overlay the generated quote text in the center of the image using an elegant serif or handwritten-style font. The text should be softly glowing, perfectly legible, minimal, and harmonious with the scene. Avoid bold, modern, or decorative typography.
