आप्तोक्तिं खननं तथोपरिशिलापाकर्षणं स्वीकृतिंनिक्षेपः समपेक्षते न हि बहिः शब्दैस्तु निर्गच्छति ।तद्वद्ब्रह्मविदोपदेशमननध्यानादिभिर्लभ्यतेमायाकार्यतिरोहितं स्वममलं तत्त्वं न दुर्युक्तिभिः ॥ ६७ ॥
In plain words
Finding a buried treasure takes a trustworthy person telling you where it is, then digging, prying away the stone lying over it, and finally taking hold of it — words alone will not bring it out. So too your own pure reality, concealed by the effects of māyā, is reached through instruction from a knower of Brahman, reflection, meditation and the rest, never through faulty reasoning.
Close to the Sanskrit
A [buried] treasure requires the word of a trustworthy person, digging, then the removal of the stone lying above it, and taking possession — for it does not come out by [mere] words. Likewise, one's own pure Reality, concealed by the effect of Māyā, is obtained through the instruction of a knower of Brahman, reflection, meditation, and the like — not through faulty reasoning.
