Sirappuli Nayanar was a pious Brahmin. He lived in Tiruvakur in the Chola kingdom. He
was an ardent devotee of Lord Siva and His Bhaktas. He used to worship them and serve them
sincerely. He would repeat the Panchakshara Mantra, with Bhav and sincerity, throughout the day
and night. He also performed the Vedic sacrifices in honour of Lord Siva. All these earned for him
the supreme grace of Siva.
A special spiritual practice of this Nayanar seems to have been the ceaseless repetition of
the Panchakshara Mantra (Om Namah Sivaya). This extremely simple practice is capable of
bestowing incalculable benefit on man: and yet, ignorant man, full of delusion, refuses to resort to
it. The continuous repetition of the Mantra will change the very mind-substance. It contains a divine
vibration. Modern science has reached a stage when it no longer believes in mass and quantity.
Even the gross and impure intellect of a scientist has come to recognise the superior power in the
subtle atom or cell. Great indeed is the foolishness of man if he still refuses to believe that the
sound-vibrations (even the subtler thought-vibrations) can bring about a radical change within
himself and heal him physically, vitally, mentally, psychically and spiritually.
This is the highest Yoga: to remember God always and constantly to repeat His Name
