I have earlier posted an article informing where the Vedic Manuscripts are available.
Siddhas, spoken of in detail in Tamil Literature.
They are Yogins, who are self realized souls.
They transcend time.
Though they have shed their physical frame, they are capable of taking new forms and are reported to be present especially in and around Thiruvannamalai,Tamil Nadu ,in Kolli ranges,Dharmapuri District,Tamil Nadu and also around Podhigai Range( Western Ghata, near Thirunelveli)
There is Chaturagiri where the temple is located and even to day there are reports of Siddhas being present there .
Please read my post on this.
The Siddhas are not only the masters of self realization, but excellent Doctors and scientists.
They are thought of eighteen in number, though they are many more.
I shall be writing more on each of them.
For general information on Siddhas please read my post on Siddhas.
Their works are found in Tamil Nadu.
