Saraswati is considered Goddess of learning, knowledge and wisdom. Saraswati Mantra and Vandana are useful to the people who want to increase their knowledge and to expand mental horizon.

Two things about mantra
A Mantra is sound waves that help to change or create conscious level as per its anatomy. There are multiple stories behind creation of any mantra. So I’d suggest just use them with the two things importantly one is “Trust” and second is “Regularity” and things will start turning into your favor.
