Perhaps it is a realisation that the world has moved on and religion is failing to keep up. Religion today is what men have made it over the centuries. The original message at the centre of religion has been perverted by egotists and bigots, for their own ends.
People need faith and spiritual belief. If not in mainstream organised religion then in an alternative experience such as Buddhism or Kabbala, or Wiccan or Paganism, hence the increase in people wandering off into the sunset to �find themselves� or questioning their beliefs.
Despite the fall in church numbers and believers, there is still anger, anxiety, greed and corruption in the world. Some bemoan the state of our society, this is a moral vacuum, spiritual hunger and a lack of values. Every day the world grows more fatalistic, cynical and disillusioned, we are more apathetic, uncaring and selfish than ever and we still kill on an unprecedented scale. War is raged for no particular reason, millions killed in genocide.
There can not be only one spiritual powerhouse in the world. With the many individual preferences, cultures, ethnic backgrounds, superstitions, beliefs and way of life it is a philosophy that could never be realised. Even if there was, would atheists or sceptics join in? If not, then the factions and intolerance would still exist as would a festering hatred leading eventually to violence or a power struggle.
