Pratyutpanna Samādhi Sūtra

The Pratyutpanna Samādhi Sūtra (Sanskrit; traditional Chinese: 般舟三昧經; ; pinyin: Bozhōu Sānmèi Jīng; Vietnamese: Kinh Bát Chu Tam Muội) is an early Mahayana Buddhist scripture, which probably originated between the 1st century BCE and 2nd century CE in the Gandhara area of northwestern India. The full title for this text is Pratyutpannabuddha Saṃmukhāvasthita Samādhi Sūtra, which translates to, "Sūtra on the Samādhi for Encountering Face-to-Face the Buddhas of the Present".

The Pratyutpanna is a particularly important Mahayana sutra in East Asian Pure Land Buddhism and Tiantai (Jp: Tendai) Buddhism, since it contains key teachings on Buddha contemplation and Buddha recollection (nianfo). It is the main source for the Tiantai school's "constantly walking samadhi" practice (taught in Zhiyi's Mohe Zhiguan), also known as the pratyutpanna-samādhi (the meditative absorption of direct encounter [of the Buddhas]). The sutra was commented on and relied upon by numerous Chinese Pure Land masters, like Huiyuan, Shandao (613–681), Cimin Huiri, and Fazhao.
