淨名經集解關中疏 2.287

2.287

時維摩詰。知其意而語言。佛說八解脫。仁者受行。豈雜欲食而聞法乎　二呵也。八解脫禪定悅食養法身也。雜欲食資毒蛇身也。人多為養毒身廢修法身。故因念以誡之。

At that time Vimalakīrti knew his thought and said to him, “The Buddha spoke of the eight liberations, which you, Virtuous Sir, have received and practice. Could you listen to the Dharma mingled with the desire for food?”
[Part] two: the rebuke. The eight liberations of meditative absorption are joyous food nourishing the dharmakāya. Food mixed with desire sustains the body of poisonous serpents. People often nourish the poisonous body to the neglect of cultivating the dharmakāya. Therefore, based on his thought, [Vimalakīrti] admonished him.
