Bhaju Ratna remarried and moved to Kalimpong, India in 1921 to start afresh as a seller of household utensils for export to Tibet. Kalimpong was then the start of the caravan route to Lhasa. As business grew, he brought over craftsmen from Kathmandu and established his own workshop.
Bhaju Ratna habitually wore a white cap, and Tibetan traders would often refer to him as Syamukapu, which means "white cap" in Tibetan. It would become the name of the business house he subsequently established in Kalimpong and Tibet.
The same name in Newari is translated to Syakar- the name of what would become one of the largest trading companies in Nepal and the sole authorized dealer of Honda vehicles in Nepal.
Saurabh Jyoti looked after trade of Phillips Sound and vision products, computer monitors, and mobile phones.
He also led the initiative for Jyoti Group to become a distributor for Unilever products from the UK through direct imports to become a distributor for products not manufactured in Nepal.
