The first thing to get under your belt are your protections: like spiritual hygiene, then you want to get into developing your astral senses and avoiding impostors and parasites…

If you feel Hecate (Greek goddess of Magick) is a good option to work with, go ahead! This is your choice, it’s often said that just feeling drawn to an entity also means they are inviting you to work with them. If you try the search, you’ll see she’s quite popular to work with and might get some ideas of how you want to go about it in terms of system or tradition.
