Skanda worship is very important in the Vedas.
While organizing the innumerable Deities mentioned in the Vedas and those followed by misinterpretations of the Vedas, Adi Shankarachatya gave the pride of place in the Shanmathas, the six systems of worship, The Kaumaram.
The Tamils speak of Lord Subrahmanya, best among Brahmins, as Murugan, embodiment of Beauty and the Tamil Language represents Lord Muruga in all his aspects.
Innumerable Hymns abound in Sanskrit,Tamil and other Regional languages of India.
Lord Subrahmanya is called as Karthikeya in India other than Tamil Nadu where he is worshiped as Murugan.
A rare stotra of Lord Kathikeya where Lord Subrahmanya Himself mentions His Twenty Eight Names, where he declares that these names would grant one Intelligence and Wisdom, among other things.
Kartikeya Pragya Vivardhana Stotra.
