You don't fully understand that person or see how best to support them. You don't know how to address social/political/environmental issues. You don't know the next step in your career. Maybe your priorities aren't clear to you. Your own behavior may be a mystery to you.
We resist not-knowing. It makes us feel uncertain and unsafe. It goes against our desire to see ourselves as wise and competent. In control.
Recognize that not knowing, if you fully admit it to yourself, can be a holy state - a place of humility, openness, and receptivity into which the divine can speak.
Today, admit that you don't know or understand. Treat your unknowing with great kindness, with a sense of curiosity.
