Reb Shlomo Carlebach elevated with music and unity so many "rituals" in Jewish observant life - like the Havdalah ("Separation") service between the end of Shabbat and the beginning of the new week. Here is the Salomon family doing a major Reb Shlomo musical and singing Havdalah with joy and togetherness. Somehow it seems this is what G-d takes great pleasure in during these times of darkness. Havdalah is bringing the light of Shabbat into the mundane weekly activities and thereby raising this material world to a divine sphere of influence ("tikkun olam").
