In your explanation, the thunderbolt is wielded by Muruga and atop airavatham.
Here are some facts, Indra was the vahanam (peacock) prior to the Lord granting that role to Suran. Airavatham's daughter is deva Kunjari (devayanai), an incarnate of Laxmi. When Indra offers himself as a vahana for the Lord, obviously, the posessions come under Muruga's asset management system.
Suran, after the war, is not annihilated. He is infact taken over as the Flag and Vehicle, a feat that is performed by Lord Vishnu on his enemies.
There is a lot more indepth to the Anubuthi, it takes a long deep look into how the master of words Guru Arunagiri has invoked the string of sentences and his choice of words too.
It has to be read in sequence. How the mapping happens vs what in essence the anubuthi is, that is extremely critical in getting the knowledge inside.
If I were to put it in a nutshell, anubuthi is bhagavat gita's essence in 51 verses in comparitively simple tamil.
Hi Ravi, After your reply , I went through all old Sanskitic sources of Skanda Myth. My understanding here is in a historical point of view not in a philosophical point of view. All Murugan Myths can be classified as pre Sangam Myths and Post Sangam myths. There is vast difference between these two myths. One feature of the post sangam myths are that it is an amalgamation of the southern myths with the northern ones. Saying that , the pre sangam sanskritic myths are basically from Ramayan and Mahabaratha. There are diff Skanda Myth version in Ramyana as well as Mahabartha. Even though both these literature were written much earlier there were lot of interpolations and final version was compiled some time during 2-3rd AD in the Gupta Period. A period close to Tamil Sangam ages.
The earliest Skanda myth occording to scholars occur in MahabarathaIII 223-232. In this myth Agni is father of Skanda. Indra tries to slays him and he attacks with his vajra but it only cuts slice of Skanda's right side and hence a new god Viska is born out of those parts and becomes part of Skanda's army. He defeats Indra and Skanda is offered the post of Indra but he declines. He is then married to Deva Sena. Here there is no reference that Devasena is daughter of Indra. There is actually a refernce earlier that wife of Indra was Sena.
Ramayana- Balakanda chapter 36-37 There is no reference of his marriage or any gifts.
Mahabaratha 9th book chapter 46 - 47 This has the first reference that Skanda recived gifts form the gods, Indra gives Dart and banner(probably vajra was the dart) Siva - army of 30,000 Sun - cock aruna - charioteer Garuda - peacock varuna - snake ganga - amirta Brahma - black deer skin
Mahabaratha 13th book chapter 84-86 Here also there is specific references to gifts, Garuda- peacock Aruna - cock Agni - ram moon - goat Varuna gives lot of animals - lion, tiger , including an elephant.
Other than this Kumarasambhava is only other imp. Skanda myth. But dating of kalidasa is around 3-6th century. Which is after Tamil sangam age. Hence there are lot of probability for influence of southern myth.
In all these northern myth, there is no exclusive reference with Skanda having an elephant as vahana. But there seems to be lot of alluded references that He might have had the Thunderbolt , vajra as his weapon.
But in Sangam literature there are many exclusive references that Murugan's vahana was elephant. eg. Kurunthokai 1.
The myth you have listed might have been a later literature so it would be extremely important to know the source of the myth you have listed and the dating of the myth.
I have read these explanations earler from murugan.org, that is just one view of Skanda. My study is southern based. Most of the data is from Skanda purana and some from translation by Thiru Vaariyar Avargal. Some are my own analysis based on various readings and thirupugazh scripts.
I had already mentioned in my earlier notes, skanda's / muruga / Karthikeya are different.
What was mentioned below is a version of skanda, as a warrior God, one of the avataars of Paramasivan.
Skaanda as Sanath kumara is a different avataar. There are two major classifications, one is of a warrior god other is as a supreme teacher.
The agni mentioned as a father of Skanda , is symbolic, like Nanda for Krishna, when Shiva embodied himself in a cosmic flame, that was borne by Agni and Vayu as no other element could hear the radiance. Skanda has no birth, He is a manifestation.
Many northern legends do not state the existance of Suran and almost all disagree on Valli. It would be like searching for Ravana in Narasmha avatar.
There are many representations, each one has their own interpretations.
There is also another theory that says Lord Krishna and Skanda are the same ( and I am not referring to the Gita's chapter 10 V 24).
Thirupugazh has wealth of information on Skanda. It calls for a deeper study, a conclusion, I am sure, would be startling.
