If a person is advancing correctly, then he is not confident or self-assured on the spiritual path. He does not arrogantly believe that he knows everything that has to happen to him and his life, but rather, he trusts only the One who governs him and makes all the actions. He knows that he must only join the One who Governs and Bestows, the Upper Ruler. That is the key to advancing correctly.
However, if a person is self-confident and proud, thinking that he knows everything, then he won’t even understand that he is on the path of a petty proprietor and that he hasn’t tasted what spirituality really is.
You shouldn’t be ashamed to admit your mistakes. The true path is when you reveal your mistakes and correct them, only to discover more mistakes, and so on.
