4.45

The Buddha told Ānanda: "After the Buddha's parinirvāṇa, those disciples of the Buddha who recall this, reflect upon this, and contemplate this phenomenon will eradicate the sins of birth and death spanning one billion two hundred million kalpas; if they wish to be reborn in pure lands of other regions, it will be according to their wish without hindrance."
