BULL STR is an arcane spell. But the psionic equivalent is also called BULL STR. since they are two different types of enhancement (one is physical (arcane) and the other is mental (psychic)) would they stack?
Read the spell description and the power description.
If they both say "an enhancement bonus to Strength", then they don't stack.
An enhancement bonus is an enhancement bonus. The source doesn't matter for stacking purposes.
