Several people dislike their few glimpses of joy. They hold themselves accountable, they hold themselves guilty for having tasted even a few drops of joy, because joy is not a socially sanctioned kind of happiness. Joy is deep, disruptive, rebellious. It takes you far away from everything into yourself. It fulfills you but does not please you. It takes you really high but at a great risk. There is no feeling of attainment accompanied with joy. So, the ego does not quite like joy.
