Power of Understanding and Wisdom in Chinese / Japanese...

悟性 means the power of understanding and insight in Chinese.

It is often associated with Neo-Confucianism. In that regard, it means to realize, perceive, or have the perception of man's true nature. It can also mean finding your soul, the soul of others, or the soul of the world. Some will translate this simply as the state of being “savvy.”

In Japanese, this is often translated as wisdom and understanding.
