We are always hearing of people who are around seeking after the Truth. I have never seen a (permanent) specimen. I think he has never lived. But I have seen several entirely sincere people who thought they were (permanent) Seekers after the Truth. They sought diligently, persistently, carefully, cautiously, profoundly, with perfect honesty and nicely adjusted judgment- until they believed that without doubt or question they had found the Truth. That was the end of the search. The man spent the rest of his hunting up shingles wherewith to protect his Truth from the weather.
Young people love what is interesting and odd, no matter how true or false it is. More mature minds love what is interesting and odd about truth. Fully mature intellects, finally, love truth, even when it appears plain and simple, boring to the ordinary person; for they have noticed that truth tends to reveal its highest wisdom in the guise of simplicity.
Use truth as your anvil, nonviolence as your hammer and anything that does not stand the test when it is brought to the anvil of truth and hammered with nonviolence, reject it.
Perhaps there is no other knowing than the mere competence of the act. If at the heart of one's being, there is no self to which one ought to be true, then sincerity is simply nerve; it lies in the unabashed vigor of the pretense. But pretense is only pretense when it is assumed that the act is not true to the agent. Find the agent.
