A. Chevy Trucks say “Like a Rock”, and Prudential Insurance advertises using a massive boulder. It symbolizes permanence in a changing world. A indestructible core upon which to depend, and seek strength in. TANYA (the classic Chabad Chassidic work of Jewish thought) shares the same Hebrew letters as EITAN which means, “old, hard and strong” – for Tanya seeks to reach, reveal and connect with the Soul within, the G-dly spark, that core within us –  which is always (hidden) there – come what may!
