As humans we have different experiences, depending on family of origin, culture, age, social class, and many other things. A person who gets the truth, plugs into the truth in a personal way. Others might also get the truth--let's say they even get the same truth--but also in a personal way. Trying to share the truth, with each other or with others, is difficult. The truth transcends language.
People have different communication styles and different human needs, and even these change over time. So the members are reduced to judging and disciplining one another according to whether they think the others are following the "truth." Fear of the organization itself, or fear of being excluded, can become more important than one's own truth.
Most organizations have some kind of hierarchy and membership requirements, meaning some people depend on someone else's truth, while others think they have the truth because they've belonged for 20 years or because they have a responsible position. Some movements try to avoid such things in various ways, but personality cults seem inevitable.
Organizations need members, so the truth might be sacrificed for the sake of growth.
It's difficult for even the most enlightened to reliably look into another's soul. So while certain paths might be recommended (e.g., chop wood, carry water; or studying under a teacher), these might not be right for a given person at a given time.
Admittedly, in our everyday lives we all have to deal with fear, personality cults, and having to prove ourselves, and these challenges may be part of our path to finding the truth. But it's our own personal struggle with these factors that helps us find the truth. Having a prepackaged version of the path robs us of the opportunity to engage in the struggle. Sure, we can fight or campaign to change things within the organization, but that distracts us from our own path.
The truth is slippery. Once you find it, your relationship with it changes--partly because you've changed. Similarly, organizations change in many ways; they might be in touch with the truth at first, but then the leader gets too old, or the new leader isn't as good as the old one, or the organization gets too big and impersonal, or withers away because of financial problems. Or maybe it no longer fits into the current external (e.g., historical) circumstance.
That's all I have for now. I'm not used to talking about these things.
