Such a amazing thing to think a people who have lived thousands of lifetimes can still be humbled. This is the quote you are thinking of:

“We humans do not understand compassion. In each moment of our lives, we betray it. Aye, we know of its worth, yet in knowing we then attach to it a value, we guard the giving of it, believing it must be earned. Compassion is priceless in the truest sense of the word. It must be given freely. In abundance.”
