Do you know that Srilanka is the first country outside of India to have Mahaperiyava Vigraham installed in a temple and that too couple of years back? During that process, they had created a mula mantra and a yantra for Mahaperiyava! Surprising, right?
Adi Sankara has a mula mantra – it goes like this:
“Om Sri sadguravE brahmavidhyAprathishtApaKacharyAya vAni pUjithAya sarVagnyAya bhArathI jethrE sri brahmanishtAya nama:”
This was done by His sishya – Sri Sureswaracharyar. Typically sishyas do it for their guru. The mula mantras typically describe the great attributes of a devata – in this case guru. Mostly a sishya would do it as they would express their experience of their guru’s great aspects. However there is no such rule that sishyas should do.
Also there are guidelines on how a yantra would be typically done – how a male vs female yantra would look, based on certain attributes – it is like a formula – one could use that formula to get a basic structure – then it would be modified for those devatas.
It is interesting that a highly learned pundit had done this for Mahaperiyava for this temple in Srilanka. More interestingly, I got access to this yantra and mantra, which was intended to go to NJ manimandapam team, which they are planning to install it during the prathistai. In my opinion, any mantra and yantra is not a secret – it is for all devotees. However they preferred not to share it for some more time. So, I am not going to share that but wanted to let you all know that a mantra exists. It will come out when it should – in the same way how I got to know that! I can give you a hint – it resembles loka mAthA’s yantra (in the document I embedded here) 🙂
Also, just go through the book – just to get an idea of how yantras look – for knowledge perspective.
Also it is NOT advisable to have yantras at home without proper guru’s guidance – particularly Sri Chakram etc. So, stay away from doing that. This post is only for academic interest purpose.
