This page keeps source-specific number 6. Sivaya also indexes the song as sequence 6. Tamil Virtual Academy describes Kaithalam Niraikani as the first special introductory Vinayagar verse and says Muththaiththaru is placed at the beginning of the main book.
Some devotional accounts describe Muththaiththaru as the first Murugan-given or first-composed verse. That is presented as traditional hagiography, not as a reason to renumber this source record.
The underlying literary text, the repository transcription, easy-reading Tamil, transliteration, translation, commentary, musical arrangement, notation, performance and sound recording are treated as separate rights layers.
No third-party recording, modern translation, notation or commentary is published from the submitted research. India-specific statutory term research does not create a universal international rights conclusion.
