He was sitting by the side of the street, watching carefully, with his begging bowl in front of him. There were of course far more interesting and complex ways for a History Monk to avoid being noticed, but he’d adopted the begging bowl method ever since Lu-Tze had shown him that people never see anyone who wants them to give him money.

“Life in this world is, as it were, a sojourn in a cave. What can we know of reality? For all we see of the true nature of existence is, shall we say, no more than bewildering and amusing shadows cast upon the inner wall of the cave by the unseen blinding light of absolute truth, from which we may or may not deduce some glimmer of veracity, and we as troglodyte seekers of wisdom can only lift our voices to the unseen and say, humbly, ‘Go on, do Deformed Rabbit… it’s my favorite’.”

The dojo master stood up. ‘Hold!’ he commanded. 'Do you not want to know the name of the man you are about to destroy?’

The fighter held his stance, glaring at Lu-Tze. 'I don’t need to know name of sweeper,’ he said.

Lu-Tze rolled the cigarette into a skinny cylinder and winked at the angry man, which only stoked the anger.

'It is always wise to know the name of a sweeper, boy,’ said the dojo master. 'And my question was not addressed to you.’

“La razon por la que la gente encuentra tan dificil ser feliz es que siempre ven el pasado mejor de lo que realmente fue, el presente peor de lo que es, y el futuro menos resuelto de lo que realmente sera.”

Lao Tzu

Deal with a thing while it is still nothing;
Keep a thing in order before disorder sets in.
A tree that can fill the span of a man’s arms
Grows from a downy tip;
A terrace nine storeys high
Rises from hodfuls of earth.
—  Lao Tzu, Tao Te Ching
