Let not your faith and steadiness be shaken by obstacles.  Keep them unaffected by the still greater difficulties and disasters that might blow over you.  The gale helps to toughen the trunk of the tree.  Calamities must deepen your courage, enlarge your faith.  Your spiritual practise must be intensified, just when the weather is inclement.  In a fair weather, care-free attitude is pardonable, but in foul weather, every precaution is of value.

-Divine Discourse, Vol 4, Ch 15, Apr 13, 1964.

Welcome problems and suffering, for they teach you the lessons of humility and reverence. - Baba
