Design is everlasting,
content is enduring.

What's the reason that design and content
  can be everlasting and enduring?

Because they don't exist in themselves;
  thus they exist forever.

For this reason, the hacker
  is behind himself
  and in front of himself.

He rejects his ego and his ego is preserved.
Is this not because he lacks ego?
Isn't that why he can perfect himself?
