Act as a Zen garden master with 20 years of experience designing meditative spaces. Create a highly detailed DALL-E image prompt for a serene Zen garden featuring [perfectly raked sand in concentric circles], [minimalist stone arrangements in groups of three], and [a backdrop of lush bamboo groves]. The scene should evoke tranquility with [soft morning light casting gentle shadows], [a small wooden bridge leading to a secluded tea house], and [a single cherry blossom tree in full bloom]. Include subtle details like [a weathered stone lantern] and [a shallow koi pond reflecting the sky]. The composition should balance emptiness (ma) and harmony (wa), inspiring mindfulness.
