As few will tell us our faults,
even if they are obvious to them,
we need to increase mindfulness of our own faults,
especially if they are not obvious to us.
Regard him as one who points out.
Treasure the wise one who seeing your faults, rebukes you.
Stay with this sort of sage.
For the one who stays with a sage of this sort, things get better, not worse.– The Buddha (Dhammapada, 6)
It is fortunate to be able to find a few or even just one true friend.
Brutal honesty with loving-kindness. Wonderful!
