The Bodhisattva of Compassion, practising zazen, sees that the five Skandha are empty, and relieves all suffering.
Okumura said that it is not me seeing that the five Skandha are empty, it is the five Skandha seeing that the five Skandha are empty.
That is, the five Skandha are not the property of the self. This body and mind does not belong to me. That being so, I cannot do other than care for it, as it is not mine. Because nothing is mine, I can take care of all beings.
So it is that the Bodhisattva of Compassion appears when Emptiness appears, when the seeing of the five Skandhas appears: everything jumps out at the same time, and always at this time. And he is the whole world.
