How are your acoustics?

This week we read the Ten Commandments. It says that there was no echo when G-d uttered these commandments. The reason: the purpose of these commandments were to make the merge of  heaven and earth, of G-dliness and physicality.  Before the Torah was given it was not possible to make something physical holy. This is why there was no echo, because G-d's voice was penetrating the entire earth, similar to a person singing in a room with proper acoustics, his voice penetrates the walls and floor and doesn't bounce back at him. Today we have the amazing power of infusing this world with gdliness, so let's take advantage of it!
