As we see from children, if things are secure, we are naturally happy – however, when we (God-forbid) develop an ego, we become miserable – the reason for this is, that we can only be happy if we are not miserable – but what is misery? (as opposed to insecurity or pain) Nothing more than anger, and what is anger, nothing less than frustration. – So why would we get frustrated? – the answer is, when we think we are more-deserving! – for if we think we are not deserving (subconsciously, but automatically) we see life as a beautiful gift – However, if we believe we are entitled to what we want (a by-product of arrogance) then we feel cheated out of what should rightfully be ours ! – this is part of the reason the jihadists are delusionally aspiring for the White House etc. etc.
