"He who is Rudra, he alone is Bhagawan (Supreme god). He is the Supreme Light and we salute him again and again".

VidyAsu SrutirutkrishTA rudraikAdaSini Srutau |

"Among all sources of knowledge (vidyas), the Vedas are supreme. In the Vedas, Sri Rudram is supreme. In the Rudram, the Panchakshari mantra (namah SivAya) is supreme and in Panchakshari mantra itself, the two syllables 'Siva' is supreme!"

Om Namah Shivay.
