I may never be able to follow that verse.
It says;
"If a wayfarer fails to find
one better or equal,
steadfast he should fare alone
for a fools no fellowship."
And is clarified as;
"People need companions. But if one does not find a person who is better than, or at least equal to oneself, it is better to be alone rather than keep company with foolish people. There is no profitable companionship with fools."
Thinking logically, if all people followed this guideline we would only have equals to deal with and we would all be very shallow friends, since as we bettered ourselves we may consider ourselves superior to our friends and then leave them behind. I can not live a life without loyalty, nor do I enjoy imagining a world without such binding morals. Nor can I believe that I, or anyone else, can judge others by intelligence since, while we may be ignorant in some things, we may be knowledgeable in others. For example, a carpenter who has not known Buddhism compared to a Buddha who has not known carpentry. The carpenter may appear ignorant to the Buddha, but know more about woodworking than the Buddha thinks there is to know. Likewise, the Buddha would have many things to teach the carpenter. Can either accurately even attempt to assess the other's knowledge? I think not, nor would I willingly live in a world where all men were arrogant enough to think themselves capable of such an act that would most likely only reflect their own ignorance.
(No, David, this was not a direct reply to you, I'm just posting this for anyone who uses the link you posted)
What I am about to share is not Buddhism, it is Taoism, but it is a verse I like for this topic. Before I post it, note that the "master" is whoever is practicing, not necessarily someone who has practiced for a long time. The "master" simply refers to you, me, and anyone else to whom it may apply.
"A good traveler has no fixed plans
and is not intent upon arriving.
A good artist lets his intuition
lead him wherever it wants.
A good scientist has freed himself of concepts
and keeps his mind open to what is.
Thus the Master is available to all people
and doesn't reject anyone.
He is ready to use all situations
and doesn't waste anything.
This is called embodying the light.
What is a good man but a bad man's teacher?
What is a bad man but a good man's job?
If you don't understand this, you will get lost,
however intelligent you are.
It is the great secret."
-Chapter 27 of the Tao Te Ching(the book I have has "sections," not chapters, but I can't very well provide a URL link for paper and ink)
I'm very glad that the Buddha did not turn away those more ignorant than himself. If he had, we would not have Buddhism today.
