A quiet mind is all you need. All else will happen rightly, once your mind is quiet. As the sun on rising makes the world active, so does self-awareness affect changes in the mind. In the light of calm and steady self-awareness, inner energies wake up and work miracles without any effort on your part
I do not suffer; I cannot suffer because I am not an object. Of course there is suffering. But do you realize what this suffering is? I am the suffering. Whatever is manifested, I am the functioning. Whatever is perceptible I am the perceiving of it. Whatever is done I am the doing of it; I am the doer of it, and, understand this, I am also that which is done. In fact, I am the total functioning.
The world is an illusion. Why is it unreal? Because none of the knowledge is going to remain permanent, as real knowledge. I had a number of identities; I was a child, I was a boy, I was a teenager, I was a middle-aged man, I was an old man. Like other identities I thought would remain constant, they never remained so. Finally, I became very old. . . So which identity remained honest with me?
By all means attend to your duties. Action, in which you are not emotionally involved and which is beneficial and does not cause suffering will not bind you. You may be engaged in several directions and work with enormous zest, yet remain inwardly free and quiet, with a mirror like mind, which reflects all, without being affected.
All you want is to be happy. All your desires, whatever they may be, are longing for happiness. Basically, you wish yourself well. . . desire by itself is not wrong. It is life itself, the urge to grow in knowledge and experience. It is choices you make that are wrong. To imagine that some little thing-food, sex, power, fame-will make you happy is to decieve oneself. Only something as vast and deep as your real self can make you truly and lastingly happy.
You must realize first of all that you are the proof of everything, including yourself. None can prove your existence, because his existence must be confirmed by you first. Your being and knowing you owe nobody. Remember, you are entirely on your own. You do not come from somewhere, you do not go anywhere. You are timeless being and awareness.
Just keep in mind the feeling 'I am', merge in it, till your mind and feeling become one. By repeated attempts you will stumble on the right balance of attention and affection and your mind will be firmly established in the thought-feeling 'I am'. Whatever you think, say, or do, this sense of immutable and affectionate being remains as the ever-present background of the mind.
