In the teaching of Helena Roerich the use of valerian is often advised. On ground of these advices I somewhere in 2008 or 2009 ordered a large amount of Indian valerian roots(Valeriana wallichii) in India, of which I drank daily a decoction. I however had the idea that it sedated my consciousness and decided to stop with it. Research in my ayurvedic literature brought to the surface that valerian is considered as tamasic and therewith indeed sedates the consciousness. I then was surprised that the use of the tamasic valerian is recommended in the teaching of Helena Roerich, and after some research I became convinced that 'valerian' in that teaching does not so much refer to the true valerian or the Indian valerian, but rather to the false valerian, better known under the name of 'jatamansi' (Nardostachys jatamansi). Jatamansi is thought to have a similar calming effect as valerian, but with the difference that jatamansi not so much sedates the consciousness but clears it. Jatamansi then is in Ayurveda considered as sattvic. Thus I switched from the use of Indian valerian to the use of jatamansi. First I took essential oil of jatamansi in use, which left a positive impression on me. The oil was in the Netherlands however very expensive, and I thought that it would be financially more favourable to order jatamansi oil in bulk in India, take from that what I needed for my own use, to then market the rest of the oil. Except jatamansi oil I ordered in bulk also jatamansi powder, deodara, mint and tulsi oil. For deodara and mint are in the teachings of Helena Roerich also adviced, and tulsi is very much appreciated in Hinduism. For the sale of the oils I set up a website with the name 'Svadeva'. Hereon I gave primary information about the oils with the possibility to order the oils in private quantities for very favourable market prices. Because in years almost nothing was sold I dismantled the website, after which the information about the oils was published under the same series name on the Arvindus website. 'Svadeva' consists of the Sanskrit words 'sva', meaning 'essence', and 'deva', meaning 'god', and 'Svadeva' refers thus to the essence of (the) god(s) or to godly essences.
