It is very important (and part of what makes Magick "work") that you pick the spell you cast on your own. Remember...everything about the spell must come from "you" for the best results.
However, I can give you some guidance on "how" to determine what spell is best for this situation.
Just click any support link on this page to open a support ticket, answer the following 2 questions:
1. What are you trying to accomplish?
2. What spells from the course have you tried so far?
Once you let me know what you've tried (and I certainly hope you've tried "something" so far.. :) ), I can better help you.
Remember...Magick is not a "science", but an art. There is no "right spell" or "perfect spell" for everybody for a given situation. It varies by person, and what feels right for you. We are all complex beings, and we must follow our hearts in the realm of Magick.
If you haven't yet, skim through the spells in the manual and find one that you feel good about. Then CAST it, and see what happens. :)
Once you are into the course and into the spell casting, I can better help you with any issues you have, but you must start and cast a spell.
I've laid out everything for you in the course...and if you feel like you don't have the experience yet to cast a spell, make sure to follow the course checklist in the "Read This First" packet of information to get up to speed with Magick and how to cast a spell.
