There are people who become disturbed the moment you laugh; they would like to teach you that life is not all play.
These people are themselves ill. They have missed life and they would not like anybody else to enjoy it. The priests are ill people; they would not like you to enjoy. They have missed; they are jealous of you.
And they have staked too much: their egos are fulfilled only because they have been against life. They have chosen ego against life. If you choose life they will be against you. They will go on curbing you, they will go on condemning you, they will go on creating guilt in you. No greater calamity, not a bigger calamity can happen to humanity as has happened through religions. The calamity is that they have created a guilty conscience.
So whenever you are enjoying, deep down somewhere you start feeling guilty, as if you are doing something wrong. Whenever you are healthy, you start feeling something is wrong.
Whenever you are dancing, you start feeling something is wrong. Whenever you laugh, you can never laugh totally because deep down something goes on pulling you back: "What are you doing?"
From the very childhood, whenever you were happy there was somebody to teach you that life is not all play: "Stop laughing! Be serious! When will you be mature? Be grown up! Enough is enough! Drop all this nonsense of childhood." Somebody was always round the corner to teach you.
They have lost: they could not enjoy so they cannot allow others to enjoy. This is how, from generation to generation, diseases are being transferred.
