A special characteristic of the (forehead plate) was that anyone who gazed upon it would be moved to feelings of remorse for his previous transgressions. These emotions often stimulated complete repentance. The Zohar states that this same characteristic also applied to one who inhaled smoke from the Ketores (incense). These are but a few examples of the exemplary form of Divine intervention which existed in the Bais Hamikdash. One needed only to seize the opportunity for complete spiritual development.
The Alter from Kelm Z”l states that this attitude was inherent in Moshe. The pasuk (Shemos 3:4) states “And Hashem saw that he turned aside to see the burning bush”. Moshe was always prepared to dedicate himself to each opportunity for spiritual advancement. This is the attitude necessary to achieve repentance and return to Hashem.
