interesting...I'm familiar with both AA and NA and have not once in my 5 years of membership heard that.
I have heard "brother fellowship"
I have also heard "big brother" and even "uncle" in reference to relationships between AA and NA.....but never "mother" until today in the above quote.
For me the third step is centered in making a decision.
cide= to kill
de= between two
This means that when I choose one way (to work the rest of the steps as they are written), the other way (my way) dies off.
When I decide to turn over my will, a power greater than me that I began believing in with the previous step 2, gives me the courage strength and guidance I need to apply honesty, open-mindedness and willingness along my journey through the rest of the steps.
Peace,
