令友所问，以果地觉，为因地心者，以阿弥陀佛所证之菩提觉道，即阿弥陀佛一句万德洪名，包攝净尽。
念佛众生，果能恳到执持憶念，则以弥陀果德，熏染自己业识妄心。熏之久久，业尽情空。
心与佛合，心与道合。全众生心，成如來藏。因该果海，果彻因源。以果地觉，为因地心，如是如是。
– 印光大师文鈔（答丁福保居士代友人問）
‘As your friend asked, on “with the effect’s [fruit] ground of awakening, as the causal ground’s mind”, with Amituofo’s realised path to Bodhi’s awakening, is “Amituofo”, this one line, with his great name of a hundred thousand virtues, that encompasses and gathers purity completely.
Sentient beings who are mindful of the Buddha’s name [“Amituofo” via Nianfo], if able to sincerely and attentively firmly [faithfully] uphold and recollect it, thus with Amituofo’s fruit of merit[orious virtues and wisdom], they gradually perfume their [negative] karmic consciousness and false mind. Perfuming for a long long time, [negative] karma will be ended and [negative] passions emptied.
The mind and the Buddha join, and the mind the path join. The whole of sentient beings’ minds, transform to the Tathagata’s treasury [Buddha-nature]. The cause is complete with the effect’s [fruit’s] ocean [of meritorious virtues and wisdom, and] the effect [fruit] pervades the cause’s source [through Nianfo]. “With the effect’s ground of awakening, as the causal ground’s mind”, such is thus.’
– Great Master Yinguang’s Letters (Reply to Layman Ding Fubao’s friend’s question)
