The Lord creates hostile forces to 
demonstrate the power of faith in 
the Divine and to confer peace and 
plenty on the believers. 
Just as a mother provides toys 
and sweets to a child for its pleasure, 
though they are of no use to her, 
God creates certain situations for 
the sake of the devotee, to bring 
out the depth of his devotion. 
Even in small matters, we find that 
their true nature is discovered only 
by experiencing the elements opposed to them. 
For instance, if one wants to develop physical strength,
he has to subject the body to strenuous exercises. 
Even a diamond requires to be cut and polished 
to enhance its brilliance and value.
