The Rebbe taught, that what goes on in the physical world, is actually a parallel of what is going on the spiritual world

It used to be, people lived very very long boring lives

Now we live lives in which change is so rapid, it is literally impossible for anyone to keep up

It used to be a person thought –as Isaac Batshever Singer (if I am not mistaken) wrote three books encapsulating all of science – so people thought, with enough patience, they could study everything

Now we know, we can never ever even explore the depth – even with all the time in the world – of a single one of God phenomenas

In other words, it used to be, people thought they were masters

Now we know, we are fortunate to be alive
