He

He who knows others is wise.
He who knows himself is illuminated.
He who defeats others is strong.
He who defeats himself is powerful.
He who knows happiness is rich.
He who keeps his path is wilful.

Be humble and you will become whole.
Bend and you will become straight.
Empty yourself and you will become full.
Wear yourself out and you will become new.

The wise man does not show off, and so he shines.
He does not make himself known, and so he is noticed.
He does not praise himself, and so he has merit.
And because he does not compete,
none in the world can compete with him.

I don’t really know whether it is good or bad to see your thoughts to be written down long ago.  They are from the book called Tao Te Ching by Lao Tzu who is considered the founder of Taoism which is a Chinese religious and philosophical tradition. You can read more about the author and the book here. You can read how the book was written  in Paulo Coelho’s blog where I saw them first.  I didn’t know the only symbol I have ever been interested is their symbol-Taijitu.
