Q: How do I become liberated/enlightened?

A: There is no you. Look and see if this is true.

Q: What does "you" mean?

A: The thing you refer to when you say or think "I", "me" or "my".

Note that you do need to be honest about this - people will often claim to believe they are X, but then use those pronouns in a way that shows they actually believe something else. For example, they say they are the body, but when their legs are cut off, they say "my legs have been cut off" rather than "I've been cut in three".

Q: What does it mean to say there's no you?

A: It means that "you" does not exist in reality, only as a thought. You can imagine a unicorn being in the room with you, but that doesn't mean an actual unicorn is there. The same is true of "you".

Q: What does it mean to look?

A: Exactly what it sounds like. If someone asks you to confirm how many toes you have, you just look and count the number of toes you see. If someone asks you to confirm if there's a tree behind you, you just turn around and look if you see a tree.

Q: Any other question.

A: Shut up and look.

Looking at your experience of life is something that you naturally do all the time. There are no questions that need answering before you can do it. There are no doubts that need allaying or philosophical issues that need dealing with before you can do it. Even if what you're going to see contradicts your beliefs, you do not need to deal with those beliefs before you can LOOK AT WHAT'S ACTUALLY THERE.

So shut up and look to see if there's a you. It's the best advice anyone will ever give you.
