यथैकस्मिन्घटाकाशे रजोधूमादिभिर्युते ।नान्ये मलिनतां यान्ति दूरस्थाः कुत्रचित्क्वचित् ॥
In plain words
Just as when the space inside one pot becomes touched by dust or smoke, the vast space elsewhere is not touched by that impurity at all.
Close to the Sanskrit
Just as when one pot-space is joined with dust, smoke, etc., other spaces situated far away do not anywhere or somehow attain impurity.
