Title question
And I found out sometimes religions keep parts of themselves secret from others does this happen in yours? Do you do this? Why?
If there be secrets, they should be temporary and something that people penetrate at the right time, at the right age or stage of life. Secrets should benefit the student.
Secrets begin with parenting. Parents put children into 'Eggs' that they much hatch from: such as school and other rites of maturing, which is what religion is part of. There are often secrets from children.
A dangerous source of secrets are charismatic individuals who pretend great virtue and power. Take for example: someone who exaggerates their ability in war or in other skills such as Smith Wigglesworth the miracle worker: In his autobiography Smith Wigglesworth claimed that God always gave him the miraculous ability to finish his plumbing work faster than other plumbers. He would say that if you believed that God would also help you, so any time you couldn't get things done it was that you needed better faith. Seriously, God even helped him with his plumbing. There is always somebody claiming to believe harder, to experience the miraculous that you can't experience, to be able to sell more than you. They make you want to give up. They put on a show like they can do the hoodoo that nobody else can, like there is something wrong with you if you can't get God to say "Hello." They have the secret you need, and its like you're a horse with the carrot suspended in front of your nose. This can go on for a long time, but even a horse eventually must eat. Sometimes they make the student give up trying to learn to learn who can never learn to do miracles or to be as fast or to be as wise as certain individuals claim to be. I think these are the deadlier secret creators in religion.
Some of these charismatic people are politicians like the leader of N. Korea or Narmer of ancient Egypt. Some are just people who get you excited about network marketing. They are everywhere. They show up in churches as the strongest believers. They set the bar so high nobody can reach it and all training is pointless. They ruin religions, companies, departments, families and entire countries (such as N. Korea).
So the point is that in this case no matter how hard you try, sometimes it will seem like you can never arrive. You can read books, do jumping jacks every morning and eat the blue pancakes but still never really be in it. Or you can pretend, and everyone will believe you are super spiritual, pat you on the back and ask how you did it.
