अभ्रेषु सत्सु धावत्सु धावन्निव यथा शशी ।तद्वदात्मनि देहत्वं पश्यत्यज्ञानयोगतः ॥ ८४ ॥
In plain words
The clouds are the ones racing across the sky, and yet it is the moon that seems to run. In just that way, through its link with avidyā, one sees bodyhood in the Self.
Close to the Sanskrit
Just as, the clouds being present and running, the moon [appears] as if running, in that same way one sees body-ness in the Self, through connection with ignorance.
