The Relationship Between Knwi and Rumi

Kūnāwi and Rumi were friends that even buried near each other in Kīnnā. So how do we reconcile to such different authors as being two outgrowths of the same Sufi tree as it were? I think that ultimately they see their goal is essentially similar even if their modes of expression and intellectual types were not the same. But one contemporary scholar, at least one that I've seen emphasizes here that Rumi doesn't say the philosophers don't have a leg to stand on. He says that they do but that it's just wooden so it's not enough to allow them to in Rumi's language fly up to the heavenly Imperium.
