Answer: It is indeed inevitable, but it can take place on two totally different levels, on the spiritual level or on the corporeal level.
It all depends on how we manage the process of our development. On the spiritual level, it will take place in the form of internal changes.
This actually will be the greatest internal war against our egoism. However, if we begin to think lightly of our internal correction, there will be an external war that will pressure us until we change our egoism and reach the same result, but with the price of large external physical losses.
