We consider 3 levels of collectors/practitioners; Beginner, Intermediate, Master.
Where you fall in these may be right on the spot or somewhere in between these descriptive titles.
Only you can really look within yourself and realize where you are in your collecting or practicing journey.
A brand new beginner would be someone who just found this way of life, someone who has none or maybe one spirit or has just begun learning and casting.
An intermediate is someone who has collected for a few months, has multiple spirits or spelled vessels or has been practicing and casting for a little while and feels reasonably comfortable with what they are doing. They still have questions but aren't in the beginning phase.
A master is someone who has been collecting or practicing for years, has a foundation of knowledge, feels very comfortable working with spirits or in their practice or casting. They have a solid base of knowledge and experience and can work with advanced spirits, spells, etc.
Most everyone falls somewhere in between. Bear in mind that in many cases if you are a beginner and you see something (spirit or spell) that is classified as intermediate you don't have to pass it up if you feel drawn to it. You will grow into it as you grow in your journey. This applies to intermediates who see something in a master level. Always know you won't be a beginner forever. Don't be afraid to push yourself and set goals.
You are not going to hurt or harm a spirit or spell more advanced than you. They realize you more than you do yourself.
