"Individuals have to suffer their Karmas but Iswara manages to make the best of their Karmas for his purpose. God manipulates the fruits of Karma but he does not add or take away from it. The subconscious of man is a warehouse of good and bad Karma. Iswara chooses from this warehouse what he sees will best suit the spiritual evolution at the time of each man, whether pleasant or painful. Thus there is nothing arbitrary."
