The Aaiyyanist diet is varied and rich. There are no rules covering eating of meat, fish etc... though traditional Dravidians do not eat beef like all mainstream Hindus. Depending on which school you belong to: you can be a strict vegan such as the S'uunya schools, or a simple vegetarian such as parts of the Aatmaani schools. Or eat meat, fish drink alcohol and take Ettaruniyyan (a highly potent drug related to DMT) as most of the Tantric schools do.
Some strict Aaiyyanist of the SainikaH school do not eat onions or garlic, or drink milk or dairy products as they believe the acidic nature of the food can affect the well-being of the gut and the spiritual sense of the person.
However, there are many Dravidian Aaiyyanists that do eat everything. As in the previous chapters in this short introduction to Aaiyyanism, the main thing to take on board is that there are no strict rules in Dravidian Aaiyyanism. We are allowed to choose how to live our life, as that is how we can fully represent the many facets of Brahman.
The reasons Aaiyyanist control their diet is simply for spiritual purposes. If one wishes to be absorbed in positive energy one can simply adhere to a vegan diet... such that no animal would be harmed. If one wants to be saturated by negative energy one can eat a meat and fish diet. If one wants to transform their mind to mimic some deeper elements of Brahman, one can take Ettaruniyyan. The change in mental faculties experienced when one drinks alcohol or takes Ettaruniyyan allows one to skirt the boundaries of positive and negative, and this mixing of resonant energy is what the Tantric Schools excel in.
Some Aaiyyanists balance the positive and negative by having a varied diet. You must understand that the ultimate aim of Aaiyyanism is to be one with Brahman and thus diet can play a part in this.
In summary there are no rigid, compulsory diet requirements that must be strictly enforced in Dravidian Aaiyyanism. This goes against the very ethos of Aaiyyanism. We are simply free to choose our own diet as that reflects the varied nature of the whole of creation that represents Brahman's will. However if you would like to restrict your diet and follow a particular Aaiyyanist School... you are free to do that also. Restriction or non-restriction is all part of the ever encompassing will of Brahman.
In a later book, I will reveal a full discourse on Aaiyyanist Diet and some traditional recipes.
