The word 'pareshaan' implies neglecting our 'shaan' i.e. the identity of being a part of the Supreme whole. When we forget about this fact, the unimportant things begin to cause us pareshaani. So we must realize that our ego is bound by destiny, not the self and ego is non-existent. For that reason devotees believe that the worldly troubles are actually His signals to draw us closer but we often fail to catch them.
