आत्मनः कार्यमाकाशो विनात्मानं न संभवेत् ।कार्यस्य पूर्णता सिद्धा किं पुनः पूर्णतात्मनः ॥ ५ ॥
In plain words
Space is something the Ātman produced; without the Ātman, space could not even arise. And the fullness of the effect is already settled — what then of the fullness of the Self?
Close to the Sanskrit
Space is an effect of the Self; without the Self it would not come into being. The fullness of the effect is established — what then of the fullness of the Self?
