The pyschologist Carl Rogers, a person who would know quite well the interior lives of others, has this to say of our inmost thoughts:
I have most invariably found that the very feeling which has seemed to me most private, most personal and hence, most incomprehensible by others, has turned out to be an expression for which there is a resonance in many people. It has led me to believe that what is most personal and unique in each of us is probably the very element which would, if it were shared and expressed, speak most deeply to others.
