Parad Shivalinga & Idols
Parad is derived from Mercury, which has undergone several stages of purification. It is the most propitious. Parad is used extensively in Vedic rituals. Idols made of Parad are considered more powerful than those of metal, wood or ceramic. A Parad Shivling is considered to have the spiritual benefits equivalent to that of a thousand stone Shivlingas.
