यद्वै तन्न वदति वदन् वै तन्न वदति ।न हि वक्तुर्वक्तेर्विपरिलोपो विद्यतेऽविनाशित्वात् ।न तु तद्द्वितीयमस्ति ततोऽन्यद्विभक्तं यद्वदेत् ॥४,३.२६ ॥
In plain words
And when it is said that he does not speak, he is speaking though he does not speak; for there is no cessation of the speaking of the speaker, since he is indestructible. But there is no second thing, separate from him, to which he could speak.
