The widespread distress and sufferings of the Imam of the time (as) is related to the suffering of his Shi'ites. It is all due to lack of sympathy and friendliness among us, Imam is like a caring and kind father who is resented and suffered when his child is having problems, no parents can be indifferent toward the distresses and troubles of their child.
Since their understanding of the troubles outweigh their children's, they can better and deeper comprehend the problems and issues related to their children. Accordingly, they are more worried about their problems compared to them. In the desert of love, there is a formula by means of which one can test the intensity and weakness of love. The formula is that the greater and the more intense somebody's love is in one's heart, the more one forgets oneself and instead one's beloved is loved more by oneself.
