In a remote and hidden valley, there is an isolated community called the Pure Light Cult. This mysterious sect believes in the purification and sublimation of the soul through extreme dieting and long fasting. They believe that only when the body is stripped to its purest state can the soul be united with the universe and enter the so-called "pure state". Every year, followers gather at the center of the sect, a simple temple built of white stones, to participate in a sacred event called the "Purification Ceremony". The ceremony lasts for 40 days. During this period, believers are required to cut off all solid food and can only drink special herbal water to completely remove impurities from the body. During this long fasting period, followers need to meditate and pray every day, striving to free themselves from the burden of the flesh. The daytime is used for reflection and introspection, while the night is led by the sect leader for collective prayer. Their low whispers echo in the silent valley, as if they are talking to some higher being. As the fast deepens, believers often experience extreme physical weakness and violent fluctuations in spirit. Some people claim to have seen visions in this extreme state, which they interpret as divine guidance or signs of spiritual sublimation. Despite the significant damage caused by extreme dieting to the body, many people continue to persevere, believing that this is a major test of faith and the only way to sublimate the soul. Believers who complete this 40-day purification ceremony will be regarded as the most devout and revered by the community. Sect leaders will also give special blessings, declaring that they have touched the "pure light" and their souls have been purified. Those who fail to persist to the end are encouraged to try again next year to continue pursuing the pure state of the soul.
