Sutra chanting, known in Chinese as song jing, is a long-standing part of Buddhist practice in which scriptures are recited aloud, often in temples, during ceremonies and in daily meditation. The practice is meant to focus the mind and honour the teachings, and its slow, repetitive delivery has made it instantly recognisable in films and online videos about temples and spiritual life. Short clips like this one circulate as sound effects because they can convey reverence and calm in less than a second, without needing dialogue or explanation.
