Every person has an image of a beautiful menorah on his face. If we draw imaginary lines between a person’s two ears, two eyes, two nostrils and mouth in the middle, we have a beautiful drawing of a menorah with seven candlesticks. The Zohar says that the holiness of the brain depends on the holiness of these seven organs, which are the seven candlesticks that illuminate a person’s brain.
The righteous men of holy spirit would look at a person and see all his deeds, whether he did sins or good deeds, for everything was revealed on the person’s face where Divine light reflects from, if he merited the illumination or if his face was darkness, all according to the seven candles. ~ R’ Shalom Arush
