This relation between thinking with spells and thinking with words is sometimes too troublesome to be taken seriously. Sometimes just saying words to myself doesn’t work, but if I’m getting to control myself with words, what harm can it be?
All it takes is for words to work is to have them bearing meaning. If I use words that I know that can have effect inside of me, then a spell is being done. It’s mostly an artificial spell, but I don’t think it is impossible to be made.
Vesta’s Spell once worked in her month back in March, when I allowed myself some pride, which helped me to get to the prosperity of May. It was a worded decision that worked in changing my feelings.
