“Where is the beauty in being frum?????”
I USED to ask baalei tshuva (when I was in high school)why they would CHOOSE to impose restrictions on themselves when they were used to having so much more “freedom.”
The answers given used to leave me floored. (It’s very obvious to me now!) They ALL felt that they had MORE freedom by having more restrictions and therefore more SELF-CONTROL. In their experience, having more self-control meant that no other force (including addictions) would have control over them. They felt more powerful and more in charge of their lives.
They also felt that even SIMPLE actions had more meaning. That thanking G-d for the food they were about to eat made the eating itself more holy.
I hope this helps.
