The Geulah is like a Vaccine
Rabbi Eliyahu Dessler Ztz’l writes that the Geulah/Chevlei Mashiach is like a vaccine.
what is in parantheses is my own addition. A translation is as follows :
“It is known that there is a refuah, that is given to a healthy person, to vaccinate them. This is when inject a small part of a specific machlah into a a person’s blood, to get the good blood fighting against sick parts of the blood (if need be.) So too in Ruchniyus, sometimes we need to have a little bit of something really Gashmiyus put into us, even when we are being ruled by our Yetzer Tov, in order that we should be able to have it ready for us to fight when we need to. (Could this be referring to the internet?)
This is why Adam HaRishon was sent into the Gashmiyus, and this is why we have the nisyonos in the Ikva D’meshicha, because the hisorirus to overcome these nisyonos will bring us to the coming of the Mashiach.
It is impossible to know something without knowing the other side of it. The only way for a person to appreciate and know Ruchniyus is to see and know how Gashmi they themselves are.
This is why we have the Ikva D’meshicha and all the darkness that comes with it.
Now that we know that we are no doubt in the Ikva D’Meshicha, we have to be very prepared to withstand all Nisyonos, and to come to an understanding and see the difference between what is out on the street, and what is a Ben Torah!”
