Smaller Sukhāvatīvyūha 17

‘Now what do you think, O Sariputra, for what reason is that repetition (treatise) of the Law called the Favour of all Buddhas? Every son or daughter of a family who shall hear the name of that repetition of the Law and retain in their memory the names of those blessed Buddhas, will be favoured by the Buddhas, and will never return again, being once in possession of the transcendent true knowledge. Therefore, then, O Sariputra, believe *, accept, and do not doubt of me and those blessed Buddhas!

‘Whatever sons or daughters of a family shall make mental prayer for the Buddha country of that blessed Amitayus, the Tathagata, or are making it now or have made it formerly, all these will never return again, being once in possession of the transcendent true knowledge. They will be born in that Buddha country, have been born, or are being born now. Therefore, then, O Sâriputra, mental prayer is to be made for that Buddha country by faithful sons and daughters of a family.
