I have been using the Heart Sutra as a banishing spell for the last couple of weeks—ranging from general feelings of nihilism to unhealthy attachments—and I LOVE it! There are so many good YouTube videos of it either being changed or put to music (my favorite embedded) and it makes the banishing fun, like I'm jamming out. The joy I get from singing it over and over reminds me that the true banishment of suffering is joy (though without attachment via hopes that it will persist forever). I feel so empowered that I can turn my own suffering around with something so simple :) Plus I love Chenrezi and all his faces!
