Sufism has been the wisdom of these poets. There has never been a poet of note in Persia who was not a Sufi, and every one of them has added a certain aspect to the Sufi ideas, but they took great care not to affront the minds of orthodox people. Therefore a new terminology had to be invented in Persian poetry; the poets had to use words such as "wine" and "bowl" and "beloved" and "rose", words which would not offend the orthodox mind and would yet at the same time serve as symbolical expressions to explain the divine law. It belongs to the work of the Sufi Movement to interpret the ideas of these poets, to express their ideas in words that can be understood by modern people, for the value of those ideas is as great today as it ever was.
