As a person living with the physical challenge of clinical dizziness, experiencing depression and its evil stepsister anxiety is a natural by product. My own experience with it has taught me some very valuable lessons.
If people were honest, they would admit that disability can be a convenient alibi, an 'out' when things get hairy. So what does all this have to do with God and PK?
Well, and PK puts this much better, God is the biggest alibi you can have in life.
One of the things, impatient, independent me has had to learn is there are a lot of meaningless things people say to you when you have something they don't get. And in India, with its culture of ignoring disability (not going to say challenged -- let's call it what it is), that's virtually the entire country!
