Thank you for sharing the girivalam video. A must for all devotees to Tiruvannamalai. It is believed that Lord Arunachala instantly pardons one’s sins upon completion of the girivalam. I thoroughly enjoyed the girivalam too in 2008!
In our teachings we're both monistic and theistic. In the beliefs of Saivism the idea of the three worlds is the basis and key to understanding temple worship, theism. The inner worlds are there to help you. The essence of the soul is already the same as the essence of God Siva, monism. You just have to find it.
