If you are caught up in fear,
you should understand and end it.
If you are caught up in desires,
you should look at yourself and understand it.
That is to say, be conscious toward various movements of your mind.
It is important to have self-recognition.
Without consciousness or self-recognition, the spirit is immature.
A person without them would understand nothing and live constantly trapped by fear and desire.
Such a life is miserable and ugly.
Accordingly, you can never mature unless you understand yourself.
Human maturity is within self-understanding and its transcendence.
Recognize your problems as they are, understand them and transcend them.
Then and only then, you grow up truly and cultivate wisdom and virtue.
