At the time of the first quarrel in the Sangha, the Buddha said:
"If you can find a trustworthy companion
With whom to walk, both virtuous and steadfast,
Then walk with him content and mindfully,
Overcoming any threat of danger.
If you can find no trustworthy companion
With whom to walk, both virtuous and steadfast,
Then, as a king who leaves a vanquished kingdom,
Walk like a tusker in the woods alone.
Better it is to walk alone:
There is no fellowship with fools.
Walk alone, harm none, and know no conflict;
Be like a tusker in the woods alone."
not sure where this came from - possibly http://www.buddhanet.net/
