Shiva Purana mentions that the secret to Sadhak Ravana’s rise to fame and closeness to Lord Shiva was Parad Shiva Ling. He was also an expert in this science and was called a Ras Siddh Yogi. He not only acquired astounding powers through this science but also converted his capital Lanka into a city of gold. He in his secret dark chamber used to offer austerities to Shiva through the worship of Parad Shiva Ling. Not only Ravana, even Banasur and other ruling dynasties secretly worshipped Parad Shiva Linga.
