“When virtue is pictured as innocence and innocence equated with childlikeness, the implication is obviously that knowledge and experience are no longer media of goodness, but have become in themselves contaminating. This is a very despairing outlook, in its way as black as Augustine's original sin, for it supposes that original goodness will in all likelihood be defiled…It surrenders the attempt to represent virtue in a mature phase.”

As quoted in The Life of Milarepa: A New Translation from the Tibetan (1977) by Tsangnyön Heruka, as translated by Lobsang P. Lhalungpa, p. 12
Context: In my youth I committed black deeds. In maturity I practised innocence. Now, released from both good and evil, I have destroyed the root of karmic action and shall have no reason for action in the future. To say more than this would only cause weeping and laughter. What good would it do to tell you? I am an old man. Leave me in peace.

Ainsi que la vertu, le crime a ses dégrés;
Et jamais on n'a vu la timide innocence
Passer subitement à l'extrême licence.
Hippolyte, act IV, scene II.
