Qigong and Reiki

Hi! I started doing Qigong, Ive heard it helps the body stay healthy, but there is something that I don't understand about it.

Why is it necessary for someone practicing Qigong or Reiki to "call upon your master" to tap into the healing energy of the Universe.

I don't get it, why do you need outide help to connect to that healing energy?

Who are they connecting to? 🤔
