Selfhood and Compassion

"All those of compassion should encourage their minds to think: 'Every living being, whether born from the womb or born in any other way, whether they have perception or none, we should bring toward the boundless freedom of liberation. And when this vast and immeasurable number of beings has been liberated, we must not believe that any being has been liberated!" Why is this? It is because no compassionate person who is truly compassionate holds to the idea of a self, a being, or a separate individual.' "
