திருமூலர் யோக இரகசியங்கள் - ஆதி மனம்

Thirumoolar is one of the 18 Siddhars. His main work is the Thirumandiram (literal meaning - ‘Sacred mantra’ or ‘Holy incantation’) that describes various aspects, from Science and Medicine to the Human aspects of Life and the Divine - Lord Shiva (PARASHIVA).
First of all Tirumoolar calls the yoga in the thirumandhiram as dhava-yoga or siva-yoga. The versus runs as follows, Siva-yoga is to distinguish the SITH from the ASITH, Yoga of penance is to attain self- illumination, Other types of yoga are not yoga proper, to attain Siva-aananda.
