Dear friends,

To pursue a query I began a few years ago and never followed up on:

Is there any scholarship that you are aware of, in the fields of Indian astrology, yoga, tantra, or medicine, on the works variously title Svarodayatantra, Śiva-svarodaya,

Svarodaya-vijñāna, etc.? I am primarily interested in older versions of these text, such as may have been in circulation before the fifteenth or sixteenth century.

I am of course familiar with Alain Daniélou's Le Shiva-Svarodaya: La naissance du Souffle de Vie (Milan 1982). Some searches on the internet have turned up a large number of modern Hindi translations and commentaries that seem mostly to be non-academic and concern popular astrology, ayurveda and the like - I imagine that the situation is similar in other modern Indian languages. (But I would welcome recommendations of works in Hindi that appear to be of value for academic research on the Sanskrit texts.)  

with thanks,

Matthew
