Gita chanting is a great stepping stone for children’s future connection with their culture.
Even if they rebel during their teenage and they seem to not care, if they have chanted and memorized in the childhood, it all comes back later.
Shloka chanting, in general, improves their memory and concentration, thereby making them better students at school. Chanting also improves their voice culture and their overall lung capacity improves.
Chanting mantras helps to heal the body, protect the mind, and manifest human desires by connecting the person who is chanting with the divine.
There are many other life changing shlokas (verses) for all aspects of life. One must go through the great book and introspect.
