न नरेणावरेण प्रोक्त एष सुविज्ञेयो बहुधा चिन्त्यमानः ।अनन्यप्रोक्ते गतिरत्र नास्ति अणीयान् ह्यतर्क्यमणुप्रमाणात् ॥ ८ ॥
In plain words
This Self, when taught by an inferior (unqualified) man, is not rightly known, however much it is debated in many ways. When taught by one who is non-different from it, there remains no further state to seek — for it is subtler than the subtle, not to be reached by mere logical inference.
