"When you subscribe to a religion, you substitute nebulous group-think for focused, independent thought. Instead of learning to discern truth on your own, you’re told what to believe. This doesn’t accelerate your spiritual growth; on the contrary it puts the brakes on your continued conscious development. "
It could be the other way around for those who choose their religion. When you substitute nebulous group-think for focused, independent thought you subscribe to a religion.
Both statements are a gross generalization. Not all people who subscribe to a religion are incapable of independent thought. The author creates a false dichotomy so he can associate his product with intelligent, independent thought.
