Without going out of your door,
You can know the ways of the world.
Without peeping through your window,
You can see the Way of Heaven.
The farther you go,
The less you know.
Thus, the Sage knows without travelling,
Sees without looking,
And achieves without Ado.
In this passage, Lao Tzu uses a house as a metaphor for the individual. Essentially, this can be summed up by saying that the spiritual path lies within, and the more that a person searches outside the self for the divine connection, the farther away one will wander from the path to enlightenment.
There’s really not much else to say about this passage. It is succinct and focused. Cheers!
