There is obviously both an external and internal dimension to this quote.
Found on many martial arts sites, it remains anonymous.
Truth can be a hard and ruthless enemy, but it's the lies that weaken and distort us.
How much truth can you bear... lightly.
But everyone believes that their own truth is true - that is a large part of the tragedy.
So it isn't so much about bearing the truth, but of finding it... and not run away.
