The Schizo World of Reiki

I've been in several Reiki social media groups off and on over the years, and after the last two I am just astounded by all the differences that exist in all these Reiki lineages.  Is there cleanse, how long does it last, what happens during it?  Are there 3 Levels of training or 4?  Is the energy that is Reiki Universal Life Force Energy or Divine Energy?  Should those who are attuned to Reiki Level II be doing Reiki on the public and charging for it, or as in some lineages only Reiki Level IIIa's (Master Practitioners)?

Is the Power Symbol supposed to be drawn CW or CCW?  Are you only supposed to be using 4 symbols if you go all the up through the levels to Master Teacher, or 7 as in some lineages, who separate the Master Level into Master Practitioner and Master Teacher. Can you use the Master Symbol (DKM for anything other than attunements, and at the Master Teacher level on yourself and for boosting Distant Reiki Healing?

And how the symbols are drown - lots of lots of variations on them, especially the HSZSN (the distant or connection symbol).  Why?  Why is someone else drawing the HSZSN this way, when my lineage or that lineage draws it differently?  Do they all work?  How can that be?  They're different!!
But apparently they do, it all does.

Who came up with the idea that the cleanse starts in the base chakra and opens/clears and balances it and then moves up to the sacral chakra and does the same, each for 24 hours, and then moves up to the next and the next?  Some lineages find this idea totally foreign, never heard of it, but yet I was taught that is how works and so I believe it and teach it.  Is that real?  Is that what is really happening?

And so on, and so on, and so on.  So, in my opinion, this makes the world view Reiki as kind of schizo, and incredible disorganized, thus less valuable then a lot of other modalities like Healing Touch  were everyone uses the same manual, teach the same things in every class, charges a lot more for training (and that's going up), and have a certification process the likes of which can be compared to presenting a Master's Thesis.  I know, I'm a Level III Healing Touch Student!

The amazing freaking thing is that IT ALL WORKS!!!!!!!!!  ??????????????????????????
