If you want to learn more about healing magic and have someone in your area who can attune you, I'd suggest looking into reiki healing. Diane Stein's book on the subject,
Essential Reiki, is only around $5 used on Amazon.
On the issue of using magick to help people, always be sure to ask permission before you perform magick for another person. You don't want to do magick that the recipient does not desire.
