"This has been my observation, that people who meditate, pray, seek and search for the truth are more prone to neurosis than other people. And the reason is: they are concerned with themselves too much, too egocentric, just continuously thinking of this and that, this block, that block, this anger, that sadness, headache, backache, stomach, legs... they are continuously moving inside. They are never okay, they cannot be, because the body is a vast phenomenon and many things go on.
And if nothing is happening then too they are worried: why is nothing happening? And immediately they have to create something because that has become their constant business, occupation; otherwise they feel lost. What to do? Nothing is happening! How is it possible that nothing is happening to me? They feel their ego only when something is happening - maybe it is depression, sadness, anger, an illness, but if something is happening they are okay, they can feel themselves."
Osho, And the Flowers Showered, Ch 10
