You Are Not The Thinking Mind
It is commonly presumed that the (apparently individual) conscious "self" is doing the thinking.
You presume that you are thinking and that you are the "subject" of that thinking.
You presume you are the source and cause and doer of thinking.
You presume that the contents, questions, and problems of your thinking are "yours"—but this is only a presumption, or a mere idea.
That presumption is not inspected—and, indeed, that presumption is not true.
Right now, you appear to be thinking—but that thinking is not actually being done by you (as you really are).
You are not the thinking mind.
Rather, you are simply the formless and actionless mere witness of whatever is arising.
