Many true statements can be said about just about anything. Thoughts and feelings, unless totally delusional, often have at least a toehold on something true.  Although sometimes the thoughts and feelings are assuming a version of reality that is just plain wrong,  often the error is in emphasis or significance.  However, to say that thoughts and feelings do not reflect reality or the truth is just too broad.  I’d rather say thoughts and feelings shouldn’t be considered as the last word, or the whole story – that they may have a basis in truth but that dwelling on some truths can prevent us from seeing other truths.
