I believe depending on your resources, a simple candle spell, wishing you or someone something. You can start by looking up color correspondences, and if you want this site will help: http://www.spellsofmagic.com/coven_ritual.html?ritual=143&coven=108 (Write the spell down in you BOS!!) Pick a color of your desired needs, then visualise your goal, and only your goal of doing the spell while writing it. It can be something easy ex.) I want some peacevor purity, and I think I need a little help. I grab a white candle. Light it, usually setting it on top of a drawn pentagram. Say something off the top of my head, or something I could have already written like. "My mind is cluttered, and I'm a mess. Lord and lady help me grant this wish. Peace of mind can help this wish. May you find my soul in a crowd, spot me, and pull me out!" Anything you want to say, can be said after chanting, or rhythmically saying that. Give thanks, I usually give a offering of juice or milk and bread! Say lots of thanks to lord and lady hearing your plea. And visualise it happening.
Hope this gives you some ideas! It's always best to write your own first spell!!
