Jalaluddin Rumi, Masnavi I Ma'navi — Book VI
“ Zulaikha was empty of self and filled with love of Yusuf, And there flowed out of her jar what it contained. The scent of the saffron of union made her smile, The stench of the onion of separation made her weep. Each to have in his heart a hundred meanings, Such is not the creed of true love and devotion. "The Friend" is to the lover as day to the sun, The material sun is a veil over the face of the real day. Whoso distinguishes not the veil from "The Friend's" face Is a worshipper of the sun; of such a one beware! ”
