Every level of truth is not less than the greatest or highest truth but in reality is a reflection of that truth. Einstein's theory of relativity pointed out that events are perceived at different angles, levels, or perspectives. The truth of that event is relative to the perceiver. Three observations made of the same event will be completely different but all are true because each observer is perceiving according to his or her own perspective. This works the same way on every level of perception.
Truth is enormous and truth is owned by the perceiver.
And so it is truly impossible for anyone else to know what is true for your self but your self. Every observation you make is a reflection of your own truth. Every bit of data that you collect, every bit of information that you gather is constantly reflecting back at you the content of your own truth. Your life circumstances constantly mirror back to you your own truth. If you want to know what your truth is, observe your existence.
