If there was only one way of understanding the 12 steps then it would not work because every person is different, what there is, is a "visual Spectrum" in which the 12 steps are in and how one understands them can go between red and violet.
And about healing going up to Nekiut, I disagree, first of all who is we you are talking about? And second of all I said what I wrote was far stretched, but here is what I really think:
1. Torah- this is the core foundation of everything because if it wasn't assur i might as well probably be masturbating right now.
2. Zehirus- That is saying to yourself "no more 'I can control it' crap!"
3. Zrizus- This is the part where we keep ourselves from sinning after we understood that
we can't fight it and only God can help us.
4. Nekiyus- That is the cleaning up process, step 4.
5. Prishus- Fences, fences, fences...
6. Tahara- Asking God to remove all of our shortcomings...step 7.
7. Chassidus- This is step 11, feeling close to God.
8. Anovoh- This is probably out of place in this context, but you need Anovoh the whole
way through.
9. Yiras Cheit- This is the second half of step 11 and also the first 3 steps, you do
not want to sin!
10. Kedusha- This is between steps 11 and twelve, you reached the point of full
healthiness.
11. Ruach Hakodesh- This is using your inner voice to guide you on the right path, step
10 must be repeated all the time.
12. Techiyas Hameisim- This is step 12.
You misght disagree and others too (and you probably will) but this is my thought and what i see in the "visual spectrum" of it all.
