Parad Shivling and Asth Sanskarit Parad
This is prepared by after completing essential 8 Sanskars. This kind of mercury is also called Asth Sanskarit Parad.
Material made from mercury like Shivling / Gutika / Mala etc. should be made from Ashta Sanskar Parad. As described in various Rasastra Sastra such as Rasendrasar, Ras Tarangini, Ras Ratna-Samuchay etc.
The various stages of the refining process of the naturally occurring mercury are called Sanskar. After the sacrament the mercury is freed from various defects and becomes divine in nature. Rubbing this Parad Mercury Shivling on clothes or on your hand will not show any kind of blackness. This is also identification / pehchan of Original Parad Shivling.
