It is hard to get anything done on earth if we are afraid of suffering. We must let go of that fear.
It is easy to suffer when we do it for a higher purpose, a higher love.
We reach a point when love and suffering become almost the same thing, because real love craves to be selfless, and selfless acts are always sacrifices, always in the attempt to relieve suffering. So by suffering, we are better able to love, better able to sacrifice ourselves, better able to draw close to God and the Spirit that resides within us.
