What role does intelligence play in spiritual enlightenment?

[Philosoraptor]

If there is to be a universal definition of intelligence, it would have to include aptitude on all of the various forms of thinking.

Ra didn't just choose to call the Creator Intelligent Infinity for no reason.

For the closest, most accurate definition, one need only investigate its etymology: intelligence derives from Latin intelligentia, "understanding, power of discerning; art, skill, taste," from intelligentem (nominative intelligens) "discerning," present participle of intelligere "to understand, comprehend," from inter- "between" (see inter-) + legere "choose, pick out."

So, once again, intelligence plays a major and prominent role in spiritual evolution.
