If we are not authentic and truthful to ourselves, we build a wall around us that eventually we have to tear down again. It is then literally a resistance to the reality and our own nature where we can hide some time, but life has a way to show us our own faults in the end.
To be true to the best one knows means to come from our own best knowledge and not buy into something outside ourselves blindly, always asking: is this really true to what I know?
In resonance with this quote also is the final one by The Buddha:
"There are only two mistakes one can make along the road to truth; not going all the way, and not starting."
