You must stop talking to yourself. Every one of us does that. We carry on an internal talk. We talk about our world. In fact we maintain our world with our internal talk. Whenever we finish talking to ourselves the world is always as it should be. We renew it, we kindle it with life, we uphold it with our internal talk. Not only that, but we also choose our paths as we talk to ourselves. Thus we repeat the same choices over and over until the day we die, because we keep on repeating the same internal talk over and over until the day we die.
A warrior is aware of this and strives to stop his talking. This is the last point you have to know if you want to live like a warrior. First of all you must use your ears to take some of the burden from your eyes. We have been using our eyes to judge the world since the time we were born. We talk to others and to ourselves mainly about what we see. A warrior is aware of that and listens to the world; he listens to the sounds of the world. He is aware that the world will change as soon as he stops talking to himself and he must be prepared for that monumental jolt.
The world is such-and-such or so-and-so only because we tell ourselves that that is the way it is. If we stop telling ourselves that the world is so-and-so, the world will stop being so-and-so. You must start slowly to undo the world.
Your problem is that you confuse the world with what people do. The things people do are the shields against the forces that surround us; what we do as people gives us comfort and makes us feel safe; what people do is rightfully very important, but only as a shield. We never learn that the things we do as people are only shields and we let them dominate and topple our lives. In fact I could say that for mankind, what people do is greater and more important than the world itself.
The world is all that is encased here; life, death, people, the allies, and everything else that surrounds us. The world is incomprehensible. We won't ever understand it; we won't ever unravel its secrets. Thus we must treat it as it is, a sheer mystery!
An average man doesn't do this, though. The world is never a mystery for him, and when he arrives at old age he is convinced he has nothing more to live for. An old man has not exhausted the world. He has exhausted only what people do. But in his stupid confusion he believes that the world has no more mysteries for him. What a wretched price to pay for our shields!
A warrior is aware of this confusion and learns to treat things properly. The things that people do cannot under any conditions be more important than the world. And thus a warrior treats the world as an endless mystery and what people do as an endless folly.
Focus all your attention on listening to sounds and do your best to find the holes between the sounds. Stay in complete alertness.
Everything is meaningful for a sorcerer. The sounds have holes in them and so does everything around you. Ordinarily a man does not have the speed to catch the holes, and thus he goes through life without protection. The worms, the birds, the trees, all of them can tell us unimaginable things if only one could have the speed to grasp their message.
Fright is something one can never get over. A warrior cannot indulge, thus he cannot die of fright. Your difficulty is that you want to understand everything, and that is not possible. If you insist on understanding you're not considering your entire lot as a human being. Your stumbling block is intact.

Understanding is only a very small affair, so very small--yet sober understanding is vital.
