如滿禪師偈
唐 佛光如滿禪師（生卒年不詳）

佛從無為來，滅向無為去，法身等虛空，常住無心處。
有念歸無念，有住歸無住。來為眾生來，去為眾生去。
清淨真如海，湛然體常寂。智者善思維，更莫生疑慮。
佛體本無為，迷情妄分別；法身等虛空，未曾有生滅。
有緣佛出世，無緣佛入滅，處處化眾生，猶如水中月。
非常亦非斷，非生亦非滅，生亦未曾生，滅亦未曾滅。
了知無心處，自然無法說。

──《景德傳燈錄》卷六

Verse by Chan Master Ruman
Foguang Ruman (Years unknown, Tang Dynasty)
English translation: Miao Hsi and Cherry Lai

The Buddha come and gone, dependent on causes and conditions. His Dharmakaya fills the universe and always resides in undeluded minds. As thoughts settle on non-thoughts, he abides in no abode, coming and going for the sake of sentient beings. Within the pure ocean of suchness, his pristine Dharmakaya exists always. The wise should contemplate as such and there is no need for any doubt.

The nature of the Buddha is beyond conditions, we differentiate due to our delusions. The Dharmakaya fills the universe and has neither birth nor death. With the right conditions, the Buddha appears in this world; when the right conditions pass, the Buddha enters parinirvana. He liberates sentient beings everywhere, like the moon in water. Neither permanent nor impermanent; no birth and no death. Lives, yet is never born; enters nirvana, yet has not ceased. When mind sees emptiness, there is no Dharma to speak of.
