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 man should not judge a man, for he harms himself very quickly, that man who judges a man.
Only I or someone like me can assess a man. --- Buddha in the Surangamasamadhi Sutra
