Thanka ,
its a Nepali form of art exported to Tibet by Priencess Bhrikuti. Its a beautifull peace of art and have become a teaching tool to illustrate life history of Gautam Buddha, Lamas, other god and goddess.
Moreover it is the visual representation of Abhidharma teaching or art of enlightenment.
This picture is made by my brother .He struggled for about 2 months and finally gave life to this wonderful art and it looks awesome.
Proud moment!!!
