十念必生願

The eighteenth vow of Amitābha Buddha is among the most important as it forms a basic tenet of the Pure Land school. This vow is most commonly known as shí niàn bì shēng yuàn (Ch. 十念必生願), because it states that if a sentient being makes even "ten recitations" (Ch. 十念 shí niàn) of the Amitābha Buddha's name they will attain "certain rebirth" (Ch. 必生 bì shēng) into the Pure Land.
