By joining the first letter of the first Thirumurai and the last letter in the last Thirumurai one can see that it is the holy 'OM'. The last word in the last thirumurai (Periya Puranam) is 'ulagelaam'. The first letter in the first thirumurai (In tamil script) is 'tho' can be separated as 'th' + 'o'. This splendid luminance has been guiding the suffering masses from their darkness to the Supreme in Whose presence the sticky bonds (pAsam) is driven off. Like the 27 stars that shine in the sky these great devotees gave the thirumuRai which are like the twelve suns (dvAdasa Adityas). The philosophers who came in the later days like the santhAna kuravas who wrote the shaiva sidhdhantha texts (1) and others like thAyumAnavar and rAmalinga vaLLalAr have adored these scriptures and their authors in their works.
