Zanabazar

Undur Geghen Zanabazar (Mongolian: Өндөр Гэгээн Занабазар, Öndör Gegeeṅ Zanabazar, "High Saint Zanabazar"; 1635–1723), born Eshidorji (Ишдорж, Išdorj), was the first Jebtsundamba Khutuktu, the spiritual head of Tibetan Buddhism for the Khalkha in Outer Mongolia. His name 'Zanabazar' is the Mongolian rendition of the Sanskrit 'Jnana-vajra' meaning thunderbolt (vajra) of wisdom (jnana). Etymologically this name would be equivalent to 'known-vigor' in English, a language genetically related to Sanskrit.
