Quotes from Rabbi Menachem M. Schneerson

Our sages have said, "Sleep is one sixtieth of death" (Talmud, Berachot 57b). If sleep is a form of death, then death is a form of sleep -- but a temporary withdrawal of vitality for the sake of reawakening to a higher quality of life

Remember that in a hall of perfect darkness, totally dark, if you light one small candle, its light will be seen from afar; its precious light will be seen by everyone.

You are going to a place of deep darkness and lies, and if you will light one candle of truth, you will dispel the darkness. (to Benjamin Nethanyahu when he became Israel's UN Ambassador)
