In East Asian Pure Land Buddhism, devotion to the Buddha Amitabha is the main practice. In Nichiren Buddhism, devotion to the Lotus Sutra is the main practice. Devotional practices such as pujas have been a common practice in Theravada Buddhism, where offerings and group prayers are made to deities and particularly images of Buddha. According to Karel Werner and other scholars, devotional worship has been a significant practice in Theravada Buddhism, and deep devotion is part of Buddhist traditions starting from the earliest days.
