Find Your Mantra Simmons recommends using a mantra (a word repeated during meditation) and in his app, the “Vibration” option is simply a wordless repetition of his suggested rhyme: “rum.” He doesn’t mean the alcohol: “Rum” is a thousand-year old mantra, and a reverberation that can be stripped of all meaning so it won’t bring up any connotation, interpretation or judgment when you hear it. “Words are static but vibrations are free,” Simmons writes in the book. “And in meditation, you always want to be free.” So every time your mind wanders or gets distracted, return to that solid syllable, choose it, and find a calm, stable place.
