We also have our month Chitra puja yesterday. One of our sishya remarked the other day: “Gurudeva is so powerfully present these days. One of our guests even said they were sure they saw him sitting right there in the temple!”
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.
