Problems help us mature fast, and make us compassionate. If you accumulate wealth and face no problem then you could be rude and unreasonable. Problems make you realise the transient nature of the possessions and reduces the gap with the person who has nothing. Death is the ultimate equaliser. Had death not been there, life would have been a series of endless torture and exploitation of one by other. In the face of problems we learn to surrender ourselves to the greater reality.
Once a devotee asked Ramkrishna, “why has God created bad people who cause problems for good ones?” Ramkrishna replied, if bad people did not exist what would be the importance of good then? The darker shade make s the light really bright. He was asked what treatment to be given to bad people? Ramkrishna suggested avoiding them, at the same time wishing them no harm. At the most the one must be careful so that there is minimum or no damage.
A snake had turned into a devoted soul, the Guru had advised it not to bite anyone. But that does not mean that it should stop hissing. Else others would kill it. Similarly one may have to put up on a hard exterior despite being a devotee. But at heart there should not be any ill feeling against anyone.
Without problems one will start thinking negatively causing harm to each other. And the destructive power of the mind is much greater than its constructive capacity. What takes decades to build, can be smashed within as second.
Remember that from dirt emerges the beautiful lotus, from scorching heat comes the shower of relief and from the depth of pain springs joy.
Hence problems can give positive results and one shouldn’t complain about them.
