Kena Upanishad 2.3

यस्यामतं तस्य मतं मतं यस्य न वेद सः | अविज्ञातं विजानतां विज्ञातमविजानताम् ॥

yasyamatam tasya matam matam yasya na veda sah | avijnatam vijanatam vijnatam avijanatam ||

To whom It is not known, to him It is known. To whom It is known, he does not know. It is unknown to those who know, and known to those who do not know.

जिसका वह अविषय है, उसी का वह विषय है; और जिसका वह विषय है, वह उसे नहीं जानता। वह जानने वालों के लिए अविज्ञात है, और न जानने वालों के लिए विज्ञात है।
