There are a lot more than 3 spiritual principals, you may be talking about Honesty Openmindness and willingness the "how"of the program. These are nice catch phrases that get tossed around in discussion meetings. I learned about spiritual principles and recovered from alcoholism by working the 12 steps of AA. Today I am aware, every thought I have, every action I take has a belief system behind. The more selfless I am the more spiritually fit I become. So far, it's proven to be a nice way for me to exist in this world.
Hardest words for an alkie or drug addict to say are I don't know. The principle of humility is underneath this, in this post you demonstrate this. Seek and you will find.
