An author, Ajit Vadakayil, has written that Shukracharya, the priest of the Asuras (who is equated to Lucifer, the Banished Angel of Light from God’s kingdom), is Ahura Mazda, but he was not the God but only the priest of the Asuras. Also, he is depicted as a man blind in one eye, and having a horse as his vehicle, which is far different from the image of Ahura Mazda, which shows him as a man with only his upper body and shoulders visible, while the lower part has wings and a plume like tail. This description of Ahura Mazda is more like Kartikeya atop his Peacock.
There is a legend that Lord Murugan came down to South India with the Kadamba rulers led by Mayur- sharman, a Shaiva Brahmin king (who later became a Jain and was known thereafter as Mayur’varman’, as the suffix ‘Sharma/n’ means ‘Brahmin’). Hence the name of Lord’Murugan’ may also have been derived from the word ‘Mayurgan’, that is, belonging to the ‘Gan (or Clan) of Mayur’- sharman, and as their ‘Gan Devta’, represented them with a stalk of the Kadamba tree in His hand. They were native rulers of Karnataka and claim to be linked with the Nanda dynasty of Magadh.(The claim of the clan of descent from Nandas is disputed, but their connection with Magadh does have truth, as the grandson of Mayursharma,Kakustha- varma(5th c. AD) is said to have entered into marital relations with the Imperial Gupta Dynasty of Magadh.
It was a later branch of the Kadambas that ruled Goa. However on being defeated by the later rulers of the region, they migrated to and settled in Tamil Nadu, where their initial deity Murugan, who was a great scholar besides being a formidable warrior, became immensely popular, in fact, as much as His brother Ganpati is in the North, or rather in West India, namely, in Gujarat and Maharashtra, and perhaps, in Madhya Pradesh too, where there are many Gujaratis and Maharashtrians!
