A few of the swamis are taking new names. Eventually, all of the monastics will have the word "natha" in their name, denoting we are all of the Nandinatha Sampradaya. This is a similar tradition as in other orders, where "ananda" or "puri" is appended to a swami's name.
We can continue to use the simple titles: swami, acharya and paramacharya when speaking with the swamis. The full, formal names are in this style: Paramacharya Sadasivanatha Palaniswami, etc. Here are the four new names to get used to:
Paramacharya Sadasivanathaswami (formerly Palaniswami)
Paramacharya Sivanathaswami (formerly Ceyonswami)
Acharya Kumaranathaswami (formerly Kumarswami, notice the added "a"
); Acharya Arumuganathaswami (formerly Arumugaswami)
The idea of Monistic Theism is seen in the three perfections of God Siva. Theism is the face of evolving, monism is always the Truth. We have pure consciousness and the source of pure consciousness, Absolute Reality. The soul body is maturing. The nucleus of your soul and Parameshvara are identical, you just have to realize it. Imkaif, Parasiva, one of the three perfections--you can't describe it.
