. I am not a Historian. I am not a Gurkha. But I was in contact with Gurkhas since I was a child. My grandmother had a Newari kind of Guest House, where most of the ex-Gurkhas including VC winners used to come and drink and sleep. Indra Jatra (Kumari Festival time was always HOUSE FULL).They used to exchange Gundrus, Nanglos and Bakhus with Pure Mustard oil. .
