In our digital world and in our digital age, one would think that one can find almost everything with a click of a mouse. This is not always the case. Here is one example. bSam-gtan-rgya-mtsho cites a certain sMyu gu’i bstan bcos ’phrul gyi sgron me. The title means something like The Magical Lamp: A Treatise on Pen. Enticing indeed! What about its whereabouts? Who composed it? When? What could it deal with? How big could it be? There are only questions and no answers yet. A website on Tibetan calligraphy shed some slight light on the topic. We have heard of the legendary figure Khyung-po g.Yu-khri. He is known for a certain style of Tibetan dBu-can script. He was a calligrapher, a scribe (yig mkhan). The Thems-spangs-ma Golden bKa’ ’gyur is said to represent the Khyung-po-g.yu-khri-lugs. Now the interesting thing is he is said to have authored two works, namely, the Rin chen sgron bu and sMyu gu’i bstan bcos ’phrul gyi sgron me. The latter seems to be extant for it is cited by bSam-gtan-rgya-mtsho. But the identity of the author as well of the work and the authorship of these works (should they surface soon) can by no means be uncritically accepted.
