The reader will be struck with the apparent want of unity in many of the
Odes. The Orientals compare each couplet to a single pearl and the
entire "Ghazal," or Ode, to a string of pearls. It is the rhyme, not
necessarily the sense, which links them together. Hence the single
pearls or couplets may often be arranged in various orders without
injury to the general effect; and it would probably be impossible to
find two manuscripts either containing the same number of Odes, or
having the same couplets following each other in the same order.
