Understand and Fail to Understand

Understand is a low-level science.
Science like water, and water just flows to the lower place,
The more he humbled his heart, the more his knowledge gained on him.

While failing to understand it is a high level of science.
He's like a gas balloon above the clouds.
He flew high with pride.
Looking down on other scientists who disagree with him,

And feel I'm the truth ... !!!
he does not have a strong foothold, so easily blown by the wind,
without being able to resist, often changing direction, without definite clarity.
Finally he was carried away everywhere until he forgot the way home, he was lost with his understanding and gradually be destroyed by pride.

Note:
The mind will function properly, when the heart feel humility.
When the heart rises, the science will blind the mind.
