“(…) Watch your mind, how it comes into being, how it operates. As you watch your mind, you discover your self as the watcher. When you stand motionless, only watching, you discover your self as the light behind the watcher. (…).”

Response to the question: "I have listened to you for many years and I have become quite good at watching my thoughts and being aware of every thing I do, but I have never touched the deep waters or experienced the transformation of which you speak. Why?"
1950s, Freedom From the Self (1955)
Context: The questioner wants to know why, after these many years of watching, he hasn't found the deep waters. Why should he find them? Do you understand? You think that by watching your own thoughts you are going to get a reward: if you do this, you will get that. You are really not watching at all, because your mind is concerned with gaining a reward. You think that by watching, by being aware, you will be more loving, you will suffer less, be less irritable, get something beyond; so your watching is a process of buying. With this coin you are buying that, which means that your watching is a process of choice; therefore it isn't watching, it isn't attention. To watch is to observe without choice, to see yourself as you are without any movement of desire to change, which is an extremely arduous thing to do; but that doesn't mean that you are going to remain in your present state. You do not know what will happen if you see yourself as you are without wishing to bring about a change in that which you see. Do you understand?

Watchers (1987)
Context: I thought of you as my guardian, Einstein… you taught me that I'm your guardian, too, that I'm Travis's guardian, and he is my guardian and yours. We have a responsibility to stand watch over one another, we are watchers, all of us, watchers, guarding against the darkness. You've taught me that we're all needed, even those who sometimes think we're worthless, plain, and dull.

First lines, Ch. 1
The Crimson Petal and the White (2002)
Context: Watch your step. Keep your wits about you; you will need them. This city I am bringing you to is vast and intricate, and you have not been here before. You may imagine, from other stories you've read, that you know it well, but those stories flattered you, welcoming you as a friend, treating you as if you belonged. The truth is that you are an alien from another time and place altogether.
