As the Christian world is divided into Papist and Protestant, and the body of Islam into Soonnee and Sheea, so also the Lamas have their two great sects, the _Gelook-pa_ and _Dok-pa_, distinguished by the colour of their caps--yellow being adopted by the former, red by the latter.[15] Celibacy is _binding_ only on the Gelook-pa, but all who aspire to superior sanctity profess it. They all abstain from taking animal life, and some of especial austerity will not even take vegetable life, deeming it unlawful to cut down a tree unless it be withered, or to gather fruit unless it be ripe. Strong drink is forbidden to all the sects. The reform which originated the sect of the Gelook-pa, now predominant over Tibet and Mongolia, and claiming the Emperor himself as one of its adherents, was the work of Tsongkhapa, a celebrated Tibetan teacher of the fourteenth century. He is traditionally stated to have derived his doctrine from a mysterious western stranger, endowed with great learning and Slawkenbergian nose. To the innovations in the Lamaitic worship introduced by Tsongkhapa, the missionaries ascribe many of the more striking resemblances to Roman ritual, and they feel inclined to believe that the mysterious stranger from the West may have been a Catholic missionary, whose teaching was imperfectly received or apprehended. The large nose they conceive may only be an indication of the European physiognomy from the Mongolian point of view. We have a counterpart portrait of the Mongolian from a Caucasian pencil, in Benjamin of Tudela, who speaks of the "Copperal Turks" as having _no noses_, but only two holes in the face through which they breathe. So also Rubruquis, when he was presented to the wife of Scacatai, a Tartar Khan, verily thought she had cut and pared her nose till she had left herself none at all! [15] The red Lamas are stated by some travellers to constitute several sects.
