Dr. David R. Hawkins, in his 2003 book, I: Reality and Subjectivity, on pages 172-174 offered a list of 12 spiritual concepts that, if absorbed and believed, offered great spiritual advancement.
These concepts are not as obvious as one might thing. It would be an obvious concept to say, for instance, that to believe in God would bring great spiritual advancement. Dr. Hawkins is more discerning than that. His concepts discuss the most valuable qualities for a dedicated spiritual seeker. From page 172,
“Start with certainty and a feeling of security instead of self-doubt or timidity. Accept without reservation that you are worthy of the quest and be resolved to totally surrender to the truth about God.
The facts that are to be unreservedly accepted are simple and very powerful. Surrendering to them brings great spiritual advancement.”
