The living teacher will bring forth the very same truth in a new light. 

“Another common misconception is that prophets, saints and mystics search for ‘new’ truth. Rather, what they do is to simply remove the layers of dirt — of accumulated misinterpretations — that have corrupted the truth. Then the living teacher will bring forth the very same truth in a new light. The original truth must repeatedly be presented to suit the current age.” (Swami Santsevi Ji Maharaj)
