Vayedaber leemor Shavuot 1969

The Alef Kabbala Group (15 May 07) discussed a discourse taught by the Lubavitcher Rebbe on Shavuot in 1969. It was edited and published in 1990. This discourse discusses the verse which introduces the Ten Commandments: "And G-d said these words, saying". What does 'saying' mean in this context? The discourse shows the tremendous force of the Giving of the Torah at Sinai as a watershed in history in terms of revealing the Divine in the physical self of each person.
