"In all your actions, words and thoughts, always regard yourself as standing before Hashem, with His Shechinah above you, for His glory fills the whole world. Speak with fear and awe, as a slave standing before his master. Act with restraint in front of everyone. When someone calls you, don't answer loudly, but gently and softly, as one who stands before his master."
