श्रवणायापि बहुभिर्यो न लभ्यः शृण्वन्तोऽपि बहवो यं न विद्युः । आश्चर्यो वक्ता कुशलोऽस्य लब्धा आश्चर्यो ज्ञाता कुशलानुशिष्टः ॥ ७॥

ॐ

English Translation

Many there are who do not even hear of Atman; though hearing of Him, many do not comprehend. Wonderful is the expounder and rare the hearer; rare indeed is the experiencer of Atman taught by an able preceptor. 

ॐ

English Commentary

Of thousands who seek good, it is some one like you who becomes the knower of the âtman; for, even for hearing, the âtman is not attainable by many; many others, though they hear of him, do not know the âtman, not being entitled, because their minds are not purified; again, the expounder of the îtman is, like a wonder, some one among many, Similarly, even among many who have so heard, some one alone of many, that is able, attains the âtman; the knower of the âtman is a wonder—some me who is instructed by an able preceptor.
