From A New Earth, by Elkhart Tolle:

• Any life-form can be said to undergo “enlightenment.” It is, however, an extremely rare occurrence since it is more than an evolutionary progression: It also implies a discontinuity in its development, a leap to an entirely different level of Being and, most important, a lessening of materiality.
• To sin means to miss the point of human existence. To live unskillfully, blindly, and thus to suffer and cause suffering.
• When faced with a radical crisis, when the old ways of being in the world, of interacting with each other and with the realm of nature doesn’t work anymore, when survival is threatened by seemingly insurmountable problems, an individual life-fore-or a species-will either die or become extinct or rise above the limitations of its condition through an evolutionary leap.
• If the structures of the human mind remain unchanged, we will always end up re-creating fundamentally the same world, the same evils, the same dysfunction.
• Suffering has a noble purpose: the evolution of consciousness and the burning up of ego.
• My enemies were doing the best they knew how to do at the time. I did the best I knew how to do at the time.
• The monster within: realize you have it; be aware when it surfaces; do not identify with it. The monster is not you; turn it into fuel for consciousness.
• I am never upset for the reason I think.
• With the grace of awakening comes responsibility. You can either try to go on as if nothing has happened, or you can see its significance and recognize the arising of awareness as the most important thing that can happen to you. Opening yourself to the emerging consciousness and bringing its light into the world then becomes the primary purpose of your life.
• As I age, my responsibility and influence to the outer world declines and re responsibility to my inner world increases.
• Old age is the time for the flowering of consciousness. Let go of external possessions, acknowledgement, status, and symbols of success in the material world.
