I declare that the overcoming of clinging to the impurities of the world is possible for a person who knows and see but not for a person who does not know or see. In the person who knows and sees, the dustless and stainless Eye of Truth arises. Seeing the truth, he sees things as they are. Seeing the truth, the eye is born, knowledge is born, wisdom is born, science is born, and light is born.

-- The Buddha, Samyutta Nikaya
