Wisdom is led by people's subjective feelings, but because of each person's subjective consciousness has different limitations. Therefore, everyone's wisdom is unilateral, not comprehensive and complete. The most common thing is that some people regard their small cleverness as wisdom and suffer a great loss. A man with great wisdom doesn't seem to be intelligent because he can make his behavior conform to the laws of heaven. So, it always seems timid and cautious.
Many people's lives are chaotic, not because they are not smart enough, but because of the limitations of their own thinking, which makes their words and deeds biased. When he only starts from his subjective feelings and limited consciousness, most of the things he does are in vain. Allah said, "he gives wisdom to those he desires; whoever gives wisdom, he has received many benefits. Only a rational person will realize it.
