Why the Lord Murugan is referred as forefather of Tamilians

 Good Question.

You must read a master piece “Tamil Pirappu Rahasyam” by one Mr N R V Appasamy in his blogspot (7 articles). It is not appreciated to give a link of it in Quora, I am providing a gist of his first article “What is in a Sound”.

It is a belief among Tamils that they are one of the first civilized society which existed before Rock and Sand in this planet. Like other socities of this holy land, they worshipped first nature, then kuldev before identified as Saivities worshipping Shiv, including its tantric rituals of Sakthism and Shaiva Siddhantam. Their agamas are pre vedic.

#According to legends, Agasthiyar got the Tamil Language from God Shiva and written Tamil Grammer and its Syntex to the Tamil people in Podhigai Hills.

#One litmus test for any classical language is its Structue with Sound (Uyir Mei Mantram), corresponding light (Visual Form) and environment (Mandalam). Simply put Mantra, Yantra and Mandalam.

#Lord of Kurinji (Podhigai Hills) is Murugan, a War God. Kurunji is one of five landscapes mentioned in Sangam literature referring to Hill and adjacent areas. He has chosen as the Yantra or Visual Form of Tamil.

Yantra [form] - Light:

The visual form of Tamil language is Lord Muruga. He is born on the day of suklapaksha (sixth day of bright half of lunar month) carried by Lord Agni (Manipuragam Chakram) with six faces (2x6 vowels; 3x6 consonants), wield a Vel (spear or ak or ayudham). His beauty can be well defined as that of sun’s rays and is considered as a war God. (Anahatam Chakram). Worshipping this form makes one Success in wars and endurance.

Mantiram [Tamil Sounds] - Sound

Visuddhi Chakram- a aa e ee u uu ae aea I o oo ou (uyir) [Communication]
Anahatam heart chakram and Manipura chakram (mei) [Warrior & Materialism]
Right – ka sa da ta pa ra (Hard consonants)
Left - ngha nggha na nha ma nhha (Soft consonants)
Swadhistanam - Ya, ra, va, la, lha, zha (Eternal consonants)
Aagya – Ak (Ayutha) (vision-trinetra)

Mandalam - Environment

The mandalam or piece of environment where it puts its ownership rights and encompasses cosmic elements of temples, art, architecture and music. The mandalam will act as an auric centre (protective seal) and the effect is now felt in the subtler dimension of consciousness of over 70 million people.

Tamizh is Murugan and

Murugan is Tamizh.

It is appropriate to consider Murugan as the Forefather of Tamizhians as they breathe Tamizh Vibrations 21600 times a day.
