I am asked on occasion how I balance out personal gnosis and research.
Honestly for me I see the two things as complementary so they just go together naturally for me. I know that there can be a perception that gnosis and existing mythology or folklore don't get along or aren't necessary to each other but for me I can't imagine having one without the other. The corpus of existing beliefs and myths are the bedrock for me and everything else comes from and is built on that. But just like an actual structure you need more than just a slab of rock and that's where the personal gnosis comes in, that's what builds things up and decorates it.
Mythology and folklore I think are indispensable and vital to my practice probably because my own life tends to have such a strong metaphysical or mystic bent to it. Researching and having knowledge of the existing folklore and the stories is an essential checks and balances system for me to help me validate things I see or experience and also to help me innovate in my own rituals and magic. And of course the beliefs of the living culture and of the written records form the bulk of my own beliefs and understanding of cosmology and theology. Researching these things can be time consuming and tedious but since we don't live in a pagan dominated culture anymore where these beliefs and stories are the norm its important to immerse ourselves as much as possible. Research becomes a way to make these things so deeply ingrained in our minds that we don't just believe them but we know them to our core, reflexively. We have to make it so that 'thinking pagan', if you will, is our natural state and that does take effort even if we aren't undoing decades of indoctrination in another religion (and I know many people are) because we live in a culture that every day reinforces materialism, monotheism, and disenchantment which are all the antithesis of animism and a polytheistic worldview.
The flip side of that is the personal gnosis, which makes up more of my daily spirituality than people might see from the outside. My spirituality is a very experiential thing but having a strong grounding in the folklore helps me filter out what is legitimate and what is just my head talking to itself. I think anytime personal gnosis is involved there is always a very real concern of both the gnosis overwhelming the person and also of a person misinterpreting the message; and of course it's very easy to convince ourselves that we are receiving something from outside that is actually just our own will or desire in one form or another. This is where its so helpful to look at the existing mythology and folklore to help filter out what is likely genuine from what is likely not. For example if I have a vision of the Morrigan urging me to be more passive and just let other people have their way with things knowing what I do of the mythology I'd be highly suspicious that this was just my head trying to give me an easy way out of a situation.
So for me research and knowledge of the mythology and folklore are less about balancing gnosis as they are about complimenting it. The two work together and guide my spirituality together. When they come into conflict its a chance for me to grow and reflect on why and how I am going to respond to that conflict.
