No sé si ya alguna vez hayas visto un águila. Claro, en el parque zoológico, pero en eso no estaba pensando. Si uno ve un águila en el zoológico, esa parece sin ganas, cansada y medio dormida. ¿Pues qué debería hacer? Un águila fue creada para volar, y eso no lo puede hacer en una jaula, en todo caso no verdaderamente. Lo que a mí me impresiona de las águilas es su fuerza y como la manejan. Se podría pensar que un ave tan grande también aleteara fuertemente cuando vuela. Pero eso no le hace falta a un águila. Traza círculos en el cielo, y aunque solo pocas veces mueve sus alas, puede subir hasta que la perdemos de la vista. ¿Cómo es que el águila sabe que es capaz de volar? Si un semejante animal pudiera hablar – creo que no empezaría a cuestionar la existencia del aire antes de ponerse a volar. Las águilas no necesitan pruebas. A ellas les basta de ser sostenidas. El resultado les sirve de prueba.
In a land in our time there lived a man, who read a book and found lots of wonderful stories therein. There were true and invented stories, experienced and pensive, enjoyable and painful stories. There were stories which contained stories, and such which were actually not stories. For every story he read, there occurred to him nearly five which he had either experienced or thought up himself. So the thought came to him, that a lot in the world was a story which could be healing for himself and others; he only needed to absorb the healing stories well and to forget the terrible ones immediately. Then he would learn which story he had used when and for what. So he organised his own stories which he knew, and which had become a help to himself and others, or could become so. Sometimes he noted it down when a new story came to his ears and sometimes when a helpful story occurred to him, he memorised it.
Then he saw before him in a picture the storystories of this life arranged in long shelves, as in a large pharmacy. And behind the counter there sat a man who had learnt to listen to himself and others. He was a master of his subjectspecialty. His talent was that he understood how to tell the right thing at the right time to himself and to those who visited him.
Some engineers are specialized in constructing valves. They do nothing else; they just construct valves, all day long. Now someone might ask: Isn’t thisit boring, to occupy your mind with nothing but valves all day long? But actually it is a very interesting field. There are valves for air and valves for steam, and then there are some for water and some for oil. There are high- pressure valves and thermostat valves. There are regulators for monitoring the temperature of a liquid, for instance in the shower. There are valves, which activate themselves and others, which can be operated only by hand, and there are some which work both automatically and manually.
One could think that valves are a human invention, but nature also knows valves and regulators of many different kinds. We find natural valves at the entrance of the gullet and of the air tube, at the exits of the stomach and of the bladder, and at the end of the intestines. Many glands are using some kind of valve. There are the heart valves, and in the veins, there are valves to ensure that the blood flows in the right direction.
We are used to turning the heat on when we are cold, and to turning it off when we are warm. We use a control for the central heating, if we want to change the temperature of the oven. We know that we can turn off the water in the house if a pipe bursts in the winter. We are used to regulating the amount and temperature of the water in the bath tub, and to accelerating and slowing down our car. We are used to our bicycle tyres being filled with air, a kettle whistling, and a steamer cooking our meals. For all this we use valves. They serve our purposes without us having to think about them. But there is one important difference between the valves of our body and the technical ones invented by humans. If a technical valve is set in the wrong position someone must come and readjust it. The natural valves of our body and soul adjust and get set all by themselves, and they can – if necessary – independently readjust themselves at any time.
