The first Reiki level is primarily aimed at self-treatment. You take the first steps towards truly getting to know yourself and your personal development of consciousness.
You will deal with your own body and your own behavior in society. As a result, you will understand the connections between body and mind and learn to perceive the messages of your body.
After all, it's not for nothing that people say "I've had enough" or "I can't take it any more". In this way, you engage in conscious, targeted self-reflection and boost your self-healing powers through self-treatment.
