Mark Epstein on saying what is true and pleasant:
Questioned some years after his enlightenment by a local prince about his penchant for delivering bad news, Buddha said that he could no longer abide by the traditional Sanskrit principle of saying only what was true and pleasant. He marched to a different drum, he maintained, and would speak of what was “true and beneficial even if it was disagreeable.” To illustrate his point, he pointed to a baby on the prince’s lap. What if the infant put a stick or a pebble in his mouth? Wouldn’t the prince pull it out even if doing so were likely to cause the baby some distress? Wasn’t that what a doctor sometimes had to do? Not to mention a mother? But he added one caveat. He would speak the beneficial, if disagreeable, truth only if he “knew the time to say it.” As is the case with good therapists today, tact was a major concern of the Buddha. If someone was not ready to acknowledge his or her trauma, he would not force the issue. Each individual had to liberate him- or herself, after all. The best a teacher, even a Buddha, can do is to show them how.
