The other morning we had a light shower moving from west to east just past Iraivan temple. When this happens when the sun is in the east we sometimes get incredible rainbows that seem so close you could almost reach out and touch them.
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.
