I believe that practical solution of world unrest is lying in the transcendental message of Sri Krishna the Personality of Godhead as given by Him lately in the Bhagavad-gita.
In this sacred philosophical discourse the Supreme Godhead declares Himself as the begetting father, who impregnates the seeds of living entities in the womb of mother nature who in turn gives birth to all varieties of living entities or species. So the plain truth is that the Supreme Godhead the Father, the nature material is the mother and all living entities are so many children of almighty father Godhead, and the mother nature. The whole arrangement is just a family unit, and we should wonder as to why there is so much anomaly in this great universal family unit.
The answer for this is also given in the Bhagavad-gita. It is said that there are two classes of men in the creation. One class is called the devas (godly) and the other class is called the asura (demonic or godless). As sons of the almighty Father Supreme Godhead, all individual living individuals have their respective independence. One can utilize this god-gifted independence properly or improperly.
