There should be immediate treatment for the wound. The Buddha's teaching is like an immediate remedy. He never tried to solve the unanswerable questions such as the beginning and end of the world etc. One nation will successfully attack another and keep the whole nation under their control, and conversely the defeated nation may counteract and enjoy the victory. This is a never ending struggle.

It is very natural for individuals to grasp what they perceive firmly. Grasping creates immeasurable troubles because we gradually become attached to what we perceive.
