पोतेन गच्छतः पुंसः सर्वं भातीव चञ्चलम् ।तद्वदात्मनि देहत्वं पश्यत्यज्ञानयोगतः ॥ ७६ ॥
In plain words
Travel by boat and it's the shore that seems to be moving. In exactly that way, joined to ajñāna, a person looks at the Self and sees a body there.
Close to the Sanskrit
To a man going by boat, everything appears as if moving; in that same way, he sees body-ness in the Self, through association with ignorance.
