Every person believes that they can spot their ego, not realizing that the person is the ego. The ego is only the sense that ‘I am a person’, which is created by believing thought.
When belief in thought is withdrawn, the oxygen supply to the person is cut off, but he still lives for a while, gasping for breath, panicking. In panic, he believes the most beautiful of thoughts: "I am God", "Belief in thought is also God's will", etc. But he cannot rely on them, and soon even these pristine thoughts are dropped.
Then he knows. Then he knows everything that can come from this mouth is only false and there is no Truth that can be spoken.
Silence is the only Truth.
