I read such a beautiful teaching of the Lubavitcher Rebbe

What do we learn for the fact that the humblest – non-boastful and non-evidentiary beautiful – mountain, Mount Sinai was chosen as the place from where the Bible / the Torah would emanate from.

Every person is like Mount Sinai, each and everyone of us has something spiritual to contribute to the entire world, yet each and every one of us is incomplete without the other, for we need to gain from their spirituality as well.
