If there is meaning in life at all, then there must be a meaning in suffering. Suffering is an ineradicable part of life, even as fate and death. Without suffering and death human life cannot be complete.
. . .
Emotion, which is suffering, ceases to be suffering as soon as we form a clear and concise picture of it.
-Viktor Frankl, Man's Search for Meaning, p. 67 and 74.
What man actually needs is not a tensionless state but rather the striving and struggling for a worthwhile goal, a freely chosen task. What he needs is not the discharge of tension at any cost but the call of a potential meaning waiting to be fulfilled by him.
-Id., p. 105.
But let me make it perfectly clear that in no way is suffering necessary to find meaning. I only insist that meaning is possible even in spite of suffering--provided, certainly, that the suffering is unavoidable. If it were avoidable, however, the meaningful thing to do would be to remove its cause, be it psychological, biological, or political. To suffer unnecessarily is masochistic rather than heroic.
-Id., p. 113
