The pure Dravidian Hindu Aaiyyanist is a person that is attempting in this lifetime (and the numerous lifetimes that they have experienced) to become one with Brahman via the science of Jnana Yoga – i.e. the Yoga of knowledge. In this regard they must study all facets of Aaiyyanist Hindu thought and philosophy. Dravidian Aaiyyanists also believe that all faiths and traditions have equal relevance and are in fact a part of Hindu Aaiyyanist philosophy.
We would not say that other religions are a subset of Aaiyyanism as that may have negative connotations and indicate some sort of hierarchy in philosophies/religions. We would say that the Hindu Aaiyyanist believes that all religions are a part or an internal truth that is embodied in Aaiyyanism, thus the way to find heaven or oneness in all faiths has the same importance. There is no one path that is more important than the other – it is simply important as Jnana Yogics to understand all methodologies. In other words there are many ways to achieve God-realisation and all truths are Universal and eternal.
You do not even have to believe in Murugan, Aaiyyan, Shiva or Brahman to be an Aaiyyanist. All that is required is that you study the texts of Aaiyyanism and understand them or reject them as you see fit. There is no strict laws that govern the Hindu Aaiyyanist – only the search for knowledge. You can be a devout Hindu, Christian, Buddhist, Muslim, Jew, or follow other beliefs. As long as you strive for spiritual unity, knowledge and your own form of enlightenment. If you do this then you are welcome in the House of Aaiyyan.
One can even study and philosophies of agnosticism and atheism and still be considered a Hindu Aaiyyanist. In fact, some factions of Hindu Aaiyyanists of the S’uunya School believe in no supreme being (as Mimamsa Hindus believe). Some Aaiyyanists philosophies reject the concept of even achieving Oneness and simple believe that when we die, we simply cease to exist. There are others in the Tantric school that have similar teachings, thus in their Tantric way they must enjoy life to the full and totally experience all that there is to do in this lifetime and this lifetime alone.
What we are trying to say is this: Hindu Aaiyyanism encompasses all thoughts and ideologies and as a practitioner it is vitally important that you study the Aaiyyanist texts and other religions, faiths, belief systems and philosophies and take them as an equal footing to the Ancient Aaiyyanist Scriptures. There is no ideology better than any other. All thoughts or philosophies just represent another way or method in interpreting this Universe and its ultimate Truth. In this regard, the Hindu Aaiyyanist is non-sectarian and embraces all peoples and ideas as part of the higher truth, even if those ideas may be contradictory. For you see, all knowledge has meaning and a place in this Universe.
Remember, all knowledge is One and that belief is what ultimately defines the Hindu Aaiyyanist.
