To be able to love one another, we must pray much, for prayer gives a clean heart and a clean heart can see God in our neighbor. If we now have no peace, it is because we have forgotten how to see God in one another.
If there is a 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.
