I will study ch. 12 of Path of Purification if need be, but I was wondering if someone knew of any scale of importance or danger for them. Are there lower or higher iddhis, such that one would focus on the higher or more useful first and avoid the lower, coarser or more dangerous iddhis?
A bodhisattva does not become weary of evil beings nor does he commit the error of bringing forth thoughts inclined to reject them and cast them aside. Avatamsaka Sutra, ch. 25
