rammala

There is a lot said on sava sadhana.

Can some one give details of sava sadhana,

Does any body practice that even today?

How is it done and with what mantra.

Aghoris do that, I was told.

Even Nil tantra talks about it as well.

Any good english version on this, please?

I am looking for a full english translation of books on Tara Vidya, to name Nila saraswathi tantrum, Brihad nilsaraswathi tantrum, tara rahasya etc.

Can any one help me to locate these or any other good work n English.

Thanks much
