को नाम बन्धः कथमेष आगतःकथं प्रतिष्ठास्य कथं विमोक्षः ।कोऽसावनात्मा परमः क आत्मातयोर्विवेकः कथमेतदुच्यताम् ॥ ५१ ॥
In plain words
What exactly is this bondage? How did it come about? What holds it in place, and how does one get free of it? What is this 'not-Self,' and who or what is the true Self beyond it all? And how do I tell the two apart? Please, explain all of this to me.
Close to the Sanskrit
What indeed is bondage? How has it arisen? What is its basis? How is release from it [attained]? What is that non-Self? What/who is the supreme Self? What is the discrimination between the two? Let this be explained.
