No mesorah
“They tell me that in Umann there is a good balance between serious and happy.”
If a person wants a good balance…. Then he should make sure to always give tzedaka with an open hand and Hashem will take care of all his needs and make sure he always had a good balance as we say in shema every day ….. If a person serves Hashem with all his soul, body and money then he will always be satisfied and his needs will always be taken care of by Hashem himself directly.
