"When the heart is completely liberated, it's impossible to deliberately harm another being. It's impossible to act acquisitively. It's impossible to take advantage of another being sexually or use your sense world indulgently. It is simply impossible. You can't lie or use speech in a harmful or deceitful way. It's as if the force of spiritual gravity won't allow it. There's nothing there that could cause you to bend the truth. . . Goodness feels good because the attitude resonates with reality. Lying and harming feel bad because they are dissonant with that reality of what we are. It's as simple as that."
Ajahn Amaro
