Only enlightened Master can have tens of billions of transformed bodies. This “transformed body”, or Tathagata or the level of onmipresence is totally exceptional. He can be anywhere and appears in multiple places at the same time. Lots of people pray to him, and he has the ability to save those prayers in countless transformed bodies. That’s why we say Quan Yin Bodhisattva will appear in a thousand places where he is prayed to. That's the real level of Quan Yin, and the real level of Tathagata, being present in all places and there’s no place without his presence. That's what it means by becoming Buddha.
The level of ultimacy is to be one with all and all sentient beings. Therefore, you can be there right away when any being prays. You will hear his prayer right away and understand it immediately once he says something, because you are one with him. That's why we say Quan Yin Bodhisattva will hear it once any being prays somewhere. We can become Quan Yin Bodhisattva if we practice Quan Yin Method. Not only Master can achieve this, you can also do it if you practice well. You can become Quan Yin Bodhisattva and be present in all places once your ego is eliminated; you are locked inside this body if you still have this “I”; you will be present everywhere if you no longer have this “I”. It’s so simple, just to break this “I”. Just like the water in this cup. It will run into the sea and become the sea once the cup is broken.
