I know what you mean and the thousands of readers that you deserve would say, YES!, but I must put my 2 cents in. Postitive from what perspective? Even if a human meets terrible adversity with love, kindness, etc., things in this Illusion could still turn out terribly shitty for the human. Too much irrational toxic positivity for me in that thought. Too much law of attraction and its victim blaming corallary for me. However, if a human does meet such adversity with spiritual principles, the soul will learn much. The soul will also learn much if the human reacts with anger, greed, etc.
I said Illusion because I have been reading and am almost finished with Richard Bach's short novel Illusions. I recommend it. I don't agree with everything in it--take what you discern as truth (as opposed to take what resonates) and leave the rest.
