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 letter "Ya" in the Panchakshara Mantra, Namasivaya, stands for the soul. Bodhinatha uses the Panchakshara Mantra to show how the soul is initially drawn by Siva's veiling grace, which leads the soul to maturity through experience in the world. Then comes Siva's revealing grace. When we've had enough of the world, Siva's grace pulls us toward God. The mantra also has the simple, two-syllable form. Si- Reflecting on God the Transcendent Absolute, Va-God as the All Pervading Consciousness
