Sure thing. I am not a Feri Witch, but Feri tradition holds that the soul has three parts: the Younger Self, the Talking Self, and the God Self. The Talking Self is what we're most familiar with on a day to day basis -- it talks, walks, makes decisions for us, tries to be logical and rational, etc. The Younger Self (also known as the Fetch) is the sort of primal, irrational self, which is more likely to understand myths, art, poetry, music, etc.; it operates on a subconscious level. So when we do ritual, that's the Talking Self attempting to communicate and access the Younger Self.
The third is the God Self, also known as the Personal God, Deeper Self, Higher Self, etc. This is the divine spark that resides within each of us. According to Feri tradition, this is the eternal part of our soul that survives beyond death, that directs us to our true calling, etc.
The trouble is that the three parts of the Soul have trouble connecting with each other (or perhaps in our society and culture we tend to overemphasize the Talking Self, to the detriment of the God Self and the Younger Self). So a central component of ritual is aligning all three Selves so that communication between them is clear and easy, and when that happens, you are at peace and also most powerful.

here. I wonder if that's what you're talking about, in terms of actualizing the God / God Self within you.
You might also be interested in archetypal theory, since you seem to have a clear idea of the kind of God Self you want to manifest -- Loki, for instance, is a classic example of the Trickster. Every archetype has its good and bad, though -- as you said, if you want to be the best you, you have to be aware of what kind of pitfalls any particular archetype might be prone to. I think one good resource is the
archetypes based off the Greek pantheon, and the
12 types of Heroes. They don't mention Loke/Loki in particular, but I'm sure you can find ways in which he relates to these.
