How Do I Become Free?

KOAN:

A student asked, “How do I get emancipated? How do I become free? How do I break my chains?”
“Who has put you in bondage?”
The student didn’t know what to do with that, so they said, “What is the Pure Land?”
“Who has defiled you and made you impure?”
“What is nirvana?”
“Who has placed you in birth and death?”
