If you don’t know the self healing techniques then you don’t know where to start. It becomes vague, and that vagueness creates doubt.
When you have more conviction, you have more faith that whatever you do is working, and therefore it will work.
Ideally, learn the healing techniques from a Master healer. Really, everyone in the world should spend some time with a great Master healer, to be exposed to healing techniques and really learn the methods of self healing.
We can also learn these things through video and other resources—you can learn a lot that way too. If anyone wants to be a healer or to heal themselves, they should be just soaking it all up, watching and learning everything they can.
