《列子·黄帝》
心灵凝聚，形体消散，骨骸血肉相互融合；感觉不到形体所倚赖的，脚下所踩踏的，只是随着风向东游西荡，就像那枯木的落叶或是竹笋的干壳四散飘零。
心凝形释，骨肉都融；不觉形之所倚，足之所履，随风东西，犹木叶干壳。
My mind was concentrated, my body vaporized, my bones and flesh fused together. I felt no dependence on my physical form, no treading beneath my feet; I only drifted along with the wind, moving east and west, like the fallen leaves of a dead tree or the dry husks of bamboos blowing away in the wind.
