佛說觀佛三昧海經 3.30

3.30

佛告阿難：「汝持佛語莫令忘失，告諸弟子，正身正意端坐正受觀廣長舌者，如我在世等無有異。若有眾生聞此說者，心不驚疑不生誹謗，不惱念佛者、勸進念佛者，供養恭敬尊重讚歎。如是等人雖不念佛，以善心故，除却百劫極重惡業，當來生處值遇彌勒，乃至樓至佛，於千佛所聞法受化，常得如是觀佛三昧。」

The Buddha told Ānanda: “Uphold the Buddha's words and do not let them be forgotten. Tell the disciples that one who rectifies their body and mind, sits upright in correct concentration, and contemplates the broad and long tongue is no different from when I am in the world. If there are sentient beings who hear this discourse and do not feel alarm, doubt, or give rise to slander, who do not vex those who practice mindfulness of the Buddha, but encourage them and offer them worship, reverence, honor, and praise—though such people may not themselves practice mindfulness of the Buddha, by virtue of their good intention they will eliminate the extremely grave evil karma of a hundred kalpas. In their future rebirths they will encounter Maitreya, and up to Rucika Buddha; in the presence of a thousand Buddhas they will hear the Dharma and receive transformation, constantly attaining this buddhānusmṛti-samādhi.”
