Greetings Indologists,

I am currently working on some Sanskrit and Tibetan material associated with the Six [Vajra]vārāhī Scriptures (phag mo gzhung drug) and the Threefold Vārāhī Cycle of the Chel Tradition (dPyal lugs phag mo skor gsum). Many of the texts associate themselves with one *Ḍākiṇī-jāla-saṃvar-ārṇava-tantra (mkha' 'gro drwa ba sdom pa rgya mtsho'i rgyud). 

Can anyone tell me more about this (attested or imagined) source text? Perhaps it is one and the same as the (equally enigmatic) Saṃvarārṇava? 

In her opus on Vajrayoginī, English (pp. 17, 52) mentions two brief references to the Saṃvarārṇavatantra among her Vajrayoginī/Vajravārāhī sources, but without any further elaboration. Moreover, in his CE of Chp. 15 of the Ḍākārṇavatantra, Sugiki (p. 3n1) notes the mention of six Arṇava texts (including Saṃvarārṇava) in a colophon to the Ḍākārṇava. However, he says, "Most likely, the Six Oceans are imaginary root scriptures." 

Besides these two references (English and Sugiki), can anyone point me towards more leads regarding the *Ḍākiṇījālasaṃvarārṇava / Saṃvarārṇava?

Thank you.
