Some good responses here.
This is like the age old question just asked re if
God is Love...so why was there the Holocaust, etc.
Does any answer or opinion really satisfy people?
Well, I don't think so if they are stuck in a cycle of worldly logic.
There is a Big Picture going on spanning lifetimes, it's a deeply spiritual situation...it is not as simple as
stating as fact: ''It's our karma''....which has been deleted here.
And why?
Because some of the highest souls, most selfless are born with birth defects on purpose...so it is said.
And it is not because they (necessarily) did some bad thing! There are reasons.
Ya wanna know some diverse reasons?
I say: Be still and understand the workings of creation more, then - because personal insight is the best and
all the answers are inside in silence waiting to dawn on you. Voila! Or,
Read people who have understood things thru years of research or meditation or NDEs, themselves.
We've got :
Many Lives, Many Masters, Dr. Brian Weiss
Journey of Souls, Micheal Newton
A World Beyond, Ruth Montgomery
All the books by Robert Schwartz, who explains it so well in simple terms...researching extensively, like many above.
Youtubes and books by Anita Moorjani -85 pounds, 4th end stage cancer, that died - came back, was healed and understood WHY she made herself sick...
Because we do have
that aspect, too...but not in all cases.
Each case has it's reasons. And there is an ultimate wonderful reason ...which is not my place to say.
That's my input anyway.
