is it a good thing to let a bochur leave yeshiva for bein hazmanim and let him face struggles that might damage the path created by his hard work this entire time, or rather create a program that is healthy and productive in what he has acquired till then and will not give him a hard time when he returns to yeshiva?
I think you answered your own question. B”h such programs already exist, but there is a need for more of them
A program can not replace being home.
For a discussion see:
Most yeshiva yungerleit are responsible and are able to use the time of bein hazmanim to renew and refresh, visit with family and engage in some of the special programs available that best meet their interests and needs. There is no single formula. Some prefer to organize their own time and others need a structured agenda. Both options are available.
It’s a great idea, but many bachurim are not interested in going to a ‘learning’ camp or program as it were, and to quote yogi Berra, if people don’t wanna come, how are you going to stop them? Many bachurim look forward to bein hazmanim as the few weeks a year when they finally can take a break from yeshiva, and would not be thanking you for this initiative. Best of luck
