I could sing a song about that – and I will sing one, although I am alone in an empty house and have to sing it to my own ears.
There are other singers, to be sure, whose voices are softened, whose hands are eloquent, whose eyes are expressive, whose hearts are awakened, only when the house is full: I am not one of them.
He who will one day teach men to fly will have moved all boundary-stones; all boundary-stones will themselves fly into the air to him, he will baptize the earth anew – as “the weightless.”

First, have a little glimpse what constitutes in you the Spirit of Gravity. All possessiveness of things makes you heavy, does not allow you to fly; it destroys your wings. I am not against using things. Use as many things as you can, but don’t possess them, because the moment you possess something, without your knowing it you are possessed by those things. A man who desires only money soon finds himself a prisoner of his own possessions. He used to think he possesses, but finally he finds he is possessed.

There is a Sufi story:

A small hut, very small, and a Sufi mystic with his wife lives there. In the middle of the night – it is raining and it is in a dark forest, wild and dangerous, too – somebody knocks on their door. The wife is near the door, sleeping. There is not much space inside, just enough for two persons to sleep.

The husband says, “Open the door. The night is dark, the forest is full of wild animals. Somebody has forgotten the way. He certainly needs refuge.”

The wife is angry. She says, “But there is no space inside our hut. There is only enough space for us two to sleep.”

The mystic laughed. He said, “It is not a palace of a king – however big the palace may be, it is always smaller than a poor mystic’s hut. Two can sleep, three can sit perfectly well. We will sit and talk and tell stories and sing songs. It is a beautiful silent night; even the rain is creating a certain music. Open the door!”

The wife opens the door. Drenched with water, a visitor enters and he says, “I am sorry to disturb you. I got lost, and I could not see any light anywhere except in your hut. I was aware it is so small, but there was no other way. Outside, life is in constant danger. The forest is full of wild animals.”

The mystic said, “There is no problem; we have enough space. Two can sleep, three can sit. And we don’t go out much and we don’t know much about the world. You are welcome. We will listen to you tell about many things that you know about the world. What we know is singing songs – we will offer you our songs, and the night will be gone soon; almost half of the night is over. Please close the doors and be at ease, and don’t feel that you have disturbed us. You have graced us; you have given us a chance to welcome a guest; you have made us richer. We are very poor people – no guest ever knocks on our doors. It has thrilled our hearts.”
