Spirituality exists, but there are two sides, even many religions speak of the dark and light side and spiritual powers.
Dark side needs secrecy because it does what people would not allow, it uses control and theft of free will by deception, the light side believes people are more good then bad, and simply showing what is done is enough to corrected things.
Education versus coercion, is part of light versus dark.
Are people more good then bad? Jefferson and Hamilton debate the question in their styles.
It is a really old debate.
To be honest, most people in what people would think of as positions of power have had intersections with spiritual power.
The thing is, spiritual power has been used so some could dominate, not to help many. By some groups, many times with them not even knowing it because they do not think and feel on their actions.
And many spiritual things are actually like this episode of Twilight Zone.
So think and feel, and be what you think and feel is best, while trying to learn, but without alowing yourself to be controlled by not thinking and feeling. They try to wipe out empathy which is love, so they can take over a person. That is why the numbness or no feeling is the goal of some of those things, but there is a good side that lets people feel and express feelings also, and builds and retains love.
The TZ episode posted is an explanation of what the dark side does.
