I think this question got lost in the shuffle, but there was a student who asked if listening to mantras is beneficial, I was wondering the same myself. They sound so intense and I like to listen to more than one, like this one https://www.youtube.com/watch?v=L3HegAD5FHI
it sounds POWERFUL. Same with the Gayatri. Since there are so many mantras, is there any advice in picking one to stick with (to use)? Should we try one for a certain period of time and then switch? I know it's advisable and proper to only use one, but is the same true for listening? Thank you so much.
