I guess the question for me specifically regarding Vedic astrology is exactly the point Valerie and Luis raise. It could be called by the astrologers 'Indian Astrology', and perhaps it is a better representation, however they have settled on the use of Vedic to qualify their predictive system. Although, it's possible that someone out there might think that 'South Asian astrology' is a better term because all this knowledge developed prior to the birth of the Indian nation.

What intrigues me is how this nomenclature sits with the practitioners of Vedic astrology, especially the ones who know the historicity but feel stuck using a term they are uncomfortable with. I have only interacted with a handful of astrologers online. Most whom I've contacted do not respond. The ones that have and have engaged with me, add to my current, anecdotal yet growing data set.

While I'm interested in the historical development of many things, it is the contemporaneous usages of the adjective 'Vedic' by various groups that interests me the most.

Probably the most intriguing expression for me at least is the utopian aspiration to "re-establish a Vedic India" http://www.vedicindiafoundation.org, the centre of which is considered to be Brahmasthanam, which is at Bijauri in nth east MP
https://vedicpandits.org This is a Maharishi enterprise.

How this is enmeshed in also, possibly, creating a Hindu nation and the way modern yoga practitioners are possibly recruited into supporting this aspiration through an 'eco-dharmic' / religious-environmentalist perspective intrigues me. Combined with the way the Indian state uses it's cultural capital and soft power through the multitrillion-dollar wellness/spiritual tourism industry is quite pertinent to my query and the logic of this induction process through the Sanskrit episteme. This is especially the case when considering particular manifestations like the 'yoga nationalism' of Ramdev and how western yoga practitioners are casually/naïvely recruited into a variety of yoga-inflected dispositions. 

For instance, yesterday a prominent yoga teacher in Sydney was shocked to know that there are Muslims in India! India, to this person, is a Hindu land full of 'spiritual people' who are all vegetarian and everyone does yoga. There are also 'some Buddhists'. Obviously this person has never been to India. Interestingly, they have no desire to either. This is not the first time I have come across people with these types of ideas.

So, for some yoga practitioners, including professional, long-term teachers, India is a type of 'Vedic/Sanskrit wonderland'. It is how this term and allied practices is infused through the social imaginary-yoga/consumption-scape that interests me the most, and what the social, political, environmental consequences might be.
