Severe destruction or shock can simply be termed as devastation. But what needed is the instinct and persistence to survive. Devastation whether natural or man-made calls for unity in action and thinking. The way one can overcome it is just to let-go of the grief, guilt and forgiving self and others for every wrong. As every day comes after night, spring after fall so is the life that springs after devastation with more vigor and understanding.
So, keep yourselves aligned with life and it will shower with all opportunities needed for better present as well as future.
