The link above is for a book that I have written. It is a sort of bible for the Order of Yeza. It's focus in more on the dark side, but it also gives info on the light as well. It's available to be read for free online.
I want to add a link for "The Book of Yeza" on amazon.com https://www.amazon.com/Book-Yeza-Merritt-Alexander-Purol/dp/1605009369/ref=sr_1_1?dchild=1&keywords=Merritt+Purol+yeza&qid=1628265447&sr=8-1
The link above is for a follow up book for the Book of Yeza. It is entitled "The Rituals and Ceremonies of the Order of Yeza". It includes a ceremony of initiation for declaring oneself as a Yezan, three rituals that coincide with the teachings of the uses of withcraft from the book of Ism, and a few other things that pertain to the Order of Yeza.
