Since Rumi was mentioned as one of the messengers of "joyful" spirituality, just for the record, Rumi extensively used the story of Joseph (as told in Quran) as a metaphor for the journey of the successful spiritual seeker. A key element of that story was the fact of 10 near-murderous 'brothers'. Also the fact that 11 stars and the sun and the moon bowed to Joseph in his dream. Rumi's mysticism very much belongs to the category of spiritual schools that assert the existence of an 'elect of spirit' among humanity, who further require 'training' under the guidance of an adept (the Pir or Elder) involving great demands on one's will power and mental states. (Which was basically the guru mentioned in the article's point.)
