He is the first, He is the last, He is the outward, He is the inward; I know none other except “Ya Hu” [Yahweh] and “Ya man Hu” [“O He who is”]. I am intoxicated with Love’s cup, the two worlds have passed out of my ken; I have no business save carouse and revelry. If once in my life I spent a moment without you, From that time and from that hour I repent of my life. If once in this world I win a moment with you, I will trample on both worlds, I will dance in triumph for ever. O Shamsi Tabriz, I am so drunken in this world, That except of drunkenness and revelry I have no tale to tell.
