I've become very interested in the reiki level 2 symbols and have been practicing them thoroughly.  It feels like a new chapter is opening up.  But, I won't lie, it aggravates me and kills my enthusiasm that I do not know which is the correct way to draw the symbols.

As far as cho ku rei is concerned, there isn't a big contradiction as I've only noticed it drawn two ways:





As we can see the second image of cho ku rei has an extra circling line.  But that isn't a big issue.  Sei he ki also has a few variations, but nothing too confusing.  Hon sha ze sho nen however is a different story and is the giant of confusion for me.  This is why...





The distance symbol has very noticeable differences and it is discouraging me.  I realize intention plays a big role in the energy frequency, but the symbols themselves carry the energy frequency and seeing such differences makes me skeptical as to which is the right way of drawing it.

Thoughts?

As Margo stated, intention is essence to use Reiki, to do healing and to use symbols.
Firstly intention !!

The frequency of symbol is transfered to atunee by his/her teacher during attunement process.
If your master teacher placed the first CKR symbol (from your pictures) to your aura, you can use this symbol's energy with that variation.
Even all different variations, if you use another CKR variation, you can not access the energy of this symbol just as you can do with your own symbol. This CKR version is anti-clockwise,also there is clockwise version. And I believe the shape of symbol effects the energy,even they have same name.
Yes, symbols you received form your master is important. But what will happen if you draw my symbols wrongly while you send healing or using Reiki? Won't healing reach to target?
No, healing will reach to person exactly in the way you send. Because you intended to send healing just as you receive the sacred information from your teacher. Maybe you draw incorrect but you did not intend to draw incorrect intentionally. Your Reiki guides corrected them for you.
But if you don't use your symbol version and try to experiment other CKR versions, you won't be access that symbol's energy just as you can do with your own. (if you don't live an placebo effect)

As you see, there is a slight nuance with the intention.

Not to live these confusions between the drawing of symbols, before this internet age, these informations and symbols were being kept as secret and weren't being shared to public. They were only being transferred from teacher to student. Because the most correct verison of a symbol is the one that is transferred to student.

But now, when we type a symbol of reiki as a word on searching engines on internet, we can find thousands of satisfying web pages (or much more) which include reiki symbols and applying informations.
Also we see in book stores, symbols are also used in the covers of reiki books freely.

Still sacred but no more secret informations and symbols of a holy healing tradition, Usui Reiki ..

An explanation on the number of turns, especially the number of nodes that it creates, finds in the image below. Words are unnecessary.

Very interesting! I know the combination number of nodes with the number of chakras.  I also heard the version with three and a half turns it because Kundalini is surrounded by three and a half times and the spiral would be the representation of Kundalini.
This is why I engage in discussions: always learn new things. Thank you Mr. Sorin.
