Spirituality is just like religion where they pretend to have knowledge beyond reason which is impossible.
When you listen to these ppl talk for long enough & analyze how their beliefs or "secret" knowledge effects their behaviors, you see it doesn't do shit but feed their egos. They don't even understand themselves.
It's an illusion to make people believe it's greater than reality and something only a special few can understand. But everyone can understand reason and morality, and morality is the true "spirituality" that only pure hearts can comprehend.
