The purpose of a consultation reading is to consult with your ancestors to understand your specific needs. This will help to ensure the success of the specific spell work that may be needed. 
All spirtual work is not created the same.
There are many different “types” of workings that can be done , the consulation will confirm and explore the specific ingredients and recipes that are specifically suited for the person and their unique needs. 
Additionally, the working that is done may be a “layered working” meaning their might be multiple steps of workings that need to be done in order to achieve spirtual goals and succes. Example, specific cleanings and protection work may be needed before proceeding to the next steps.
In conclusion to the consultation reading, 
If you would like me to do the work on your behalf, I will confirm with spirit for permission to do the work on your behalf.
