I am healing myself all the time, only I don't know it.
When my knee hurts I rub it with my hand. I am transferring pure energy from my hand to my knee. That's self healing.
When you cut your finger you put it in your mouth. No one has taught you, but your saliva contains an antiseptic.
When someone tells you something you don't like, you fold your hands across your chest and block your solar plexus. The solar plexus is the center for negative emotions. No one has taught you that. You just know it.
All this is done by the spiritual self.
Please comment below, I would be happy to discuss my views further.
