Many Aaiyyanist scholars have debated this question. The obvious answer is that Aaiyyanism was founded by Aaiyyan. But who is Aaiyyan?
There are several answers to this question. The first one is that Aaiyyan is an incarnation of Shiva. His first incarnation. This is believed my many Aaiyyanist Schools such as the Kaaryakartaa and the SainikaH Schools. Other mainstream Schools such as the Aatmaani believe that Aaiyyan is the offspring of Shiva and Parvati, i.e. their child – but much more than this. Aaiyyan is the blending of the masculine and feminine aspects of GodHood and so is neither male nor female. Other Dravidian Schools also equate Aaiyyan with Murugan – i.e the son of Shiva and Parvati.
I and many other scholars personally believe that all of this is true. Aaiyyan is the incarnation of Shiva, the descendant of Shiva in the form of Murugan and is the Universal combination of Shiva and Parvati to create a new being that surpasses them both and creates a new aspect of Brahman that did not exist in the confines of Brahman before.
Suffice it to say, the message of Aaiyyanism was directed by Aaiyyan and was spread throughout the ages in the many incarnations of Aaiyyan/Murugan.
The first incarnation of Aaiyyan Murugan was around 70,000 – 100,000 years ago (according to Dravidian Aaiyyanist Historians). It was a time when the human species was quite young and the spiritual and material world was much closer than it is now. It was also a time before ‘The Block’ Surapadman was placed that separated these worlds and dimensions. It was in this first incarnation that the young humans were taught the ancient language of Dravidian Aaiyyani, a language and script so powerful that it was (and still is) able to unlock the doors between different realities.
In this reality there is not just this Universe and its energies. There are countless positive (Lokas) and negative (Talas) dimensions that surround our one. These dimensions exists outside of our space and time but some are closer to ours than others. Brahman persists in all of the dimensions (realities) but Brahman’s essence can be found in the centre. Murugan Aaiyyan taught humanity how to use the scripts of Dravidian Aaiyyani to inscribe areas of space that would resonantly link with other areas of space/time in near and far dimensions. Thus, when you inscribe this information or language the portals are opened to other Lokas and Talas and resonant energy can flow between those planes to ours. Aaiyyan taught us how to use these energies to affect our own reality and others. Aaiyyan Murugan taught us how to use the resonant energies to heal, see into the distant past and future, how to travel (via astral projection) to those planes and to other worlds. Aaiyyan taught us how to converse with beings that exist in those realms, including the Higher Gods. By conversing with the Higher Gods one can prayer more effectively and directly with the Supreme Beings that govern our Universe and many others.
To put it more simply, Aaiyyanists believe that Aaiyyan Murugan taught humans the key to unlocking this Universe by understanding how the spiritual flow of energy and matter can change our reality. From this teaching of Dravidian Aaiyyani: all things follow. Thus, once humans had mastered the language of the Gods, Aaiyyan then taught Humans the philosophy of the Universe and how we are all one with Brahman. Aaiyyan Murugan taught us how to live our lives via the various schools of philosophy and how to eat, pray, expand our consciousness, meditate, perform sacred rituals, remember our past lives and how to liberate ourselves from this reality.
Once Aaiyyan taught us this knowledge, humanity used this wisdom for thousands of years. Thus, the golden age of Dravidian Aaiyyanism was born until it was destroyed in the Kallaaiyan incident. The Aaiyyanist community was spilt and dwindled for many thousands of years.
Aaiyyan Murugan then returned a second time after the Aryan invasions of the Dravidian lands to re-educate humanity via the teachings of Aaiyyan. This was in 1500 BC. Some of the original Aaiyyanist practitioners were around when Aaiyyan reemerged in 1500 BC and this small community spread the teachings to the non-Dravidians and it is this first step that has resulted in Aaiyyanists existing, praying, teaching, healing and practising throughout the world in so many different countries today.
