佛說觀佛三昧海經 4.15

4.15

The Buddha told Ānanda: "After the Buddha's parinirvāṇa, disciples of the Buddha who make this contemplation will eliminate extremely heavy evil karma of a thousand kalpas. In the place of their future rebirth, their minds will be unattached; they will not abide in a womb, but will constantly be born by apparitional birth (aupapāduka). Once born by apparitional birth, their bodies will be fully endowed with light and they will never be parted from the Buddhas. Such contemplation is called right contemplation; if one contemplates otherwise, it is called wrong contemplation.
