Shin Buddhism, also known as Jodo Shinshu, is a branch of Pure Land Buddhism founded by Shinran Shonin in the 13th century in Japan. It emphasizes reliance on the compassion of Amida Buddha, who promises to save all beings who sincerely call upon his name. Followers believe that through this faith, they can attain enlightenment and be reborn in the Pure Land. The practice of Shin Buddhism centers on the recitation of the nembutsu, which is the phrase "Namu Amida Butsu," expressing gratitude and devotion to Amida Buddha. Unlike other forms of Buddhism that focus on personal effort for enlightenment, Shin Buddhism teaches that salvation comes through faith and the grace of Amida.
