काचभूमौ जलत्वं वा जलभूमौ हि काचता ।तद्वदात्मनि देहत्वं पश्यत्यज्ञानयोगतः ॥ ८२ ॥
In plain words
A glass floor shows you water; a sheet of water shows you glass. In just this way, one looks at the Self and sees a body — through contact with ignorance.
Close to the Sanskrit
On a glass floor, waterness; or on a water surface, indeed, glassness — like that, in the Self one sees bodyhood, from conjunction with ignorance.
