What the Rav said:
It’s well known that a person needs to be very careful to be happy always, and to distance himself from any type of sadness no matter how small.
Through sadness, a person only ends up falling into greater sins.
Even if a person stumbled in some sin, he should immediately grab a Tehillim, he should immediately go and dance, find some friends and dance with them.
Because, if he falls into sadness from this [the fact that he sinned], he’ll just fall into greater sins.
My thoughts:
The Rav teaches us here that happiness is a weapon.
It’s probably the most powerful weapon we have against the yetzer hara.
I think its Rabbenu who said that more than the sin itself, the yetzer hara really wants a person to fall into sadness and despair.
Because, then it’s game over.
So, know, that happiness is your weapon. It can save your life!
We’re going to sin. It’s a given fact. We need to get used to it and work out a battle strategy to fight back.
Happiness, and dancing, are two of the biggest weapons in your arsenal.
Don’t forget it! :-)
