On fast Sunday or when we fast can we fast for more than one purpose on that day?
I have on occasion, had more then one purpose in mind while fasting. Life doesn’t always come at you in a nice orderly manner that allows you to focus on just one thing at a time. That being said I think we should try to have just one if we can. But I say this due to human limits on being able to focus and ponder, not due to any divine limits or requirements.
