How Siththars protected their body from mortality? -Thirumoolar

                In kundalini yoga, when the Yogi raises the internal heat in the nerve-plexus upwards through suzhimunai mummandalam* (three zones) will also grow simultaneously. After mummandalam have grown completely, human body won’t get destroyed till the end of the Earth, says Thirumoolar. 

“கொண்ட விரதம் குறையாமல் தான் ஒன்றித்

konda viratham kuraiyaamal thaan onri

தண்டுடன் ஓடித் தலைப்பட்ட யோகிக்கு

thandudan oadi thalaipatta yogikku

மண்டலம் மூன்றினும் ஒக்க வளர்ந்தபின்

mandalam moonrinum okka valarnthapin

பிண்டமும் ஊழி பிரியாது இருக்குமே

pindamum oozhi piriyaathu irukkumae.” 

- திருமூலர் (Thirumoolar) 

               “To get rid of mukkunam* (three qualities), the darkness, the gas named abaanan in mooladhara (pelvic plexus) should be raised and the right side sooriya kalai should be synchronized with left side santhira kalai. If you practice like this for 24 minutes daily in the morning, Lord Shiva will bless you with immortality” says Thirumoolar. 

Hence it is clear from Thirumoolar’s words that Siththars lived for many years.

*Mummandalam - Akkini mandalam, sooriya mandalam, santhira mandalam

*Mukkunam - Thaamasam, Rajaasam, Sathveegam
