Asking for an easy spell is like asking "What's an easy astrophysics class?". If you don't know the basics none of them are easy or even possible. Make sure you learn other stuff first. Spells are all advanced magic. You'll need more than grounding and centering, you'll need to learn to manipulate energy, visualize and most importantly to shield yourself. Mail me if you have questions about any of them. If you've already done all that then you can try any spell you want. Usually you get better results if you make your own spells.
