The Ganesha vigrahas in Flushing, New York temple and the Dodda Ganapati temple in Basavanagudi, Bangalore need to be compared before labeling this Great Ganapati in Coiamabtore as the biggest vigraha. Jai Ganesha.
Ahhh, but surely it is not the size of the murthi, but the power of the life-changing energy from within it that counts. I would much rather have a 2 inch murthi that winks at me, understanding my every karma, than a gargantuan one that feels empty. Jai Ganapati
Trying to compare is not enough to get to the answer of your question.
As the prayer- Aum Shuklam Baradharam Vishnum….- goes on, we shift our mind to praise the Gods aspects of being divine moonlight that exist everywhere(omnipresence) and his four great shoulders etc. Can we ever imagine how big is everywhere for His Omnipresence? Of course no, because the mind cannot give that reality, its beyond the mind, that is its you, as a soul, equal to everyone and everything as Parasivam…
I tried to answer it, though that question brings me to the worlds of infinities.:)
In our teachings we're both monistic and theistic. In the beliefs of Saivism the idea of the three worlds is the basis and key to understanding temple worship, theism. The inner worlds are there to help you. The essence of the soul is already the same as the essence of God Siva, monism. You just have to find it.
