Setting an image of a power spot as your wallpaper can dramatically improve your health luck. Power spots are places where Earth's energy is concentrated, including popular shrines, temples, and natural landmarks. For instance, images of Kiyomizu-dera in Kyoto, Zenko-ji in Nagano, or the Jomon Sugi in Yakushima possess powerful energy. Using images of these locations as your wallpaper is believed to attract not only health luck but also overall good fortune. Especially, images of power spots you have personally visited are said to have an even stronger effect.
