One patient asked me:
- Why is God sending me so many bad times ? Am I so bad ?
- The correct question to ask is not "Why ?", but "What for ?" , - I corrected him.
The annoyances and troubles have been given to you not because you are bad, but because you must improve yourself and become even more (i.e. better) than what you are now.
