I am attending a Mussar Vaad which costs $560 for the year (I’m a female)
I’d like to take a course on Emunah which costs $100 for one time
I might want to take other courses for my personal growth in Torah and Hashgafa.
Can these classes be paid for with Maaser?
Maaser is essentially intended to be used to give to poor people. According to some opinion it can be used for mitzvos, however this is only if the person can otherwise not afford to do the mitzva. Even so it should not be used for personal use.
