Rudrabhishekam is one of the most venerable form of Shiva worship. Shiva being abhisheka priya in his ever resplendent form, it is performed regularly. Within a set of ways of doing Rudrabhishekam, another sought after method is Eka Vara Rudrabhishekam. In this form, mahanyasa sravanam, rudra prashna are recited.
To perform this abhisheka, a specific yantra is prepared using highly fertile black mud. In fact, in Hindu system, there is varna system even in mud. It is believed that white color soil has to be used for jnana, red color for victory in war and protection from enemies, green soil* for wealth and prosperity, black soil for sukha (comforts).
This is called Kailasa Yantram. It consists of a total of 366 linga rupas. It has 11 avaranas. Each Avarana has a presiding deity. The yantra itself is a representation of Kailasa and each Avarana is an entrance into it. Presiding deity of each Avarana is worshiped along with Eeswara and Eeswari. In fact during the process, explicit permission is sought from each deity at each Avarana to go inside kailasa and perform abhisheka. Abhisheka literally means to pour as a thin “dhaara”. Visualize Bhageeratha Prayatna and Ganga pouring into Shiva’s jata. There are explicit and very detailed explanations of ekavara rudrabhishekam in various commentaries in Shiva Worship.
Know what you do when you worship. Hindus are not sheep and we dont have a sheperd. This is because for us, worship is only a way of experiencing paramatma within the self. Learn traditions. We have a heritage that we should be proud of. Own it. Experience it. Cherish it and pass it on to the next generation.
