नैवात्मापि प्राणमयो वायुविकारोगन्तागन्ता वायुवदन्तर्बहिरेषः ।यस्मात्किञ्चित्क्वापि न वेत्तीष्टमनिष्टंस्वं वान्यं वा किञ्चन नित्यं परतन्त्रः ॥ १६८ ॥
In plain words
The prana-sheath is not the Self either. It is simply a modification of air, moving in and out the way wind does. It knows nothing at all -- not what is pleasant or unpleasant, not what belongs to it or to someone else, nothing whatsoever -- and it always depends on something beyond itself.
Close to the Sanskrit
The prana-sheath is also not the Self at all; it is a modification of air, going and coming like the wind, within and without. Because it knows nothing anywhere -- neither the desirable nor the undesirable, neither its own nor another's, anything at all -- it is always dependent on something else.
