Eye can only see something if
idea about it has been in mind.

Eyes can only capture objects that already seen in mind.
And mind can only see things that already written in heart.

A solid idea is a firm foundation of a universe construction.

Don't live in regret! It is such a useless idea.
Use the memory to prevent us do bad things!
Regret is a childish wish, or an empty hope,
trying to revise the bitter memory of the past.

At beyond continent of reality, there are ocean of ideas.

Eyes shows lies.
