I will paste somethings in Vedanta which was analyzed by my friend which is pretty clearly indicative that Swami Vivekananda was perfectly right. In particular reference to what Balls has asked .For once I disagree with his views

* Balls' quote :
1."Everything in the world is good, is holy and beautiful"-think abt it ... were the English good when they plundered our rich country? Is Conversion holy?
2."If you see something evil, think that you are not understanding it in the right light"-Cant be more ridiculous...i see someone being ruthless murdered...does he expect me see the good in that?
3."Throw the burden on yourselves!"-Y shud i do that when sumone else has machiavellian instincts

Underlying Concept: The world can be called as a dream. The world exists in the mind. When our mind stops working the world does not exist for us (eg. SLEEP). Mind is temporary and when a person has realized God his mind dissolves. So when the mind is dead then where is the question of this world. Does this world exist for a person who is in deep Samadhi. The only thing he sees is God, Divine light, bliss.

To answer Balls' question : If we are all God’s divine pieces, we do not need him at all. If whole world is pervading Brahma, there should be no hell, no war, no problems, no pain.
Answer : Why cant Brahma manifest itself as pain, suffering and problem. Why does it always have to manifest itself as pleasure, happiness, peace. As long as you see pleasure, you will see pain. Once your are above pleasure, then pain wont also affect you. Again all these are the states of the body and the soul is pure.
Nainam chhindanti shastraani, nainam dahati paavakah,
Na cha enam kledayanti aapah, na shoshayati maarutah".This is a shlok from the Geeta describing the soul. Pain and Pleasure mean nothing for a realized person. If you ask this same question to an advaitist he will say “War, problems and pain belong to your body and this world. When there is no world then where is the question of all these things”

I know I am not well read on this issue but I am trying to be.Though it is a totally spiritual perspective of viewing at the question I think it qualifies as an answer.
