WISE COUPLETS

The book you got in your hands is composed of couplets that convey hidden thin messages. Some of them you are familiar with, but others you aren't. Additionally some of them are fiction as well. Without exception, as soon as you read, they leave an exceptional taste in your mind. As it goes in an old saying, 'You learn something new whenever you open the page of any book' From this, you'll pick up countless new things even on each page but not one thing only. As they are rhymic, it's enjoyable to read practical to memorize, thanks to being short. As to how right I am, I think the following couples will give you a clue.
AGAIN
But don't say that's not happening.
Stand firm, again and again, trying.
UPDATE
Update yourself now and then.
Look around; you're just a human.
PROOF
A proof that you are alive,
That's a warm heart; it's why.
EQUALS
One of us and the other,
Our value is equal to each other.
MOTHER
For the origin of this world emerged high.
As far as I know, this world is the mother of the lie.
