Vanakkam. When I saw the presence of Jutikadevi at the avudaiyar site, it brought tears in my eyes. Avudaiyar is the Parashakti portion of the Sivalingam, and the thought came to me that Goddess Parvathi came down to earth in the form of Jutikadevi to add Her Shakti through adding the gold. Iraivan Temple is wonderful.
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.
