We can know the energy of wisdom. When you use your wisdom, you think how to do better and what to do better. You think, right? How do you feel at that time? You can know the mental state.
We make choices the whole day – what does the choosing? Craving or not? Is it defilement choosing or wisdom choosing?
The mind thinks how to do better – beneficial or not, need or not, necessary or not. When the mind is thinking like this, at that time the energy is wisdom.
