A Vedantic tenet in a Muthuswamy Dikshitar's composition

[V Subrahmanian]

In this composition about Sri Sundararaja Perumal (Nāgapaṭṭinam, T.N.), this line appears:

अनृत-जड-दुःखापहम्   = He who frees us from the three-fold misconception of 'false-insentient-misery'.

This triad is popular in Advaita Vedanta.  The idea is: While we are Sat-Chit-Ananda/Ananta in truth, we are under the delusion that we are the opposite. We have several references to this in Advaita works:

Here is a gloss of Anandagiri in the Nyāyanirṇaya for Shankara's Brahma Sūtra Bhāṣyam: 3.3.12:

सत्यज्ञानादयो मिथो विशेषणविशेष्यभूता विरुद्धानृतजडादिभ्रान्तिं निवर्तयन्तः ..

Satyam, Jnanam, etc. (anantam/anandam) which are mutually adjective-substantive, remove the delusion of their opposites namely anr̥tam (false), jaḍa (insentient), duḥkha/paricchinna (miserable/limited)...

The Kalpataru on the Bhāmati:

सत्यज्ञानानन्दानन्तात्मत्वपदार्था इतरेतरं विशेषणविशेष्यभूता विरुद्धानृतजडदुःखपरिच्छेदानात्मताभ्रान्तीर्व्यावर्तयन्तः

(similar to the earlier quote..)

Those unfamiliar with the Advaitic tenet above give different meanings to the अनृत-जड-दुःखापहम् in the song. 

Sri Dikshitar is well known for bringing out Advaitic doctrinal points in several of his compositions.
