Mantra are usually word refining out into pulses. The video above does something that I can't quite explain. Try learning the pattern, it's a simle 3:2 beat, an easy polyrhythm. I know Sanskrit was composed of patterns to represent syllables and that drum beats played on Indian percussion are actually words/phrases and not how we understand rhythm in the West.
Just tapping out this beat synchronises with something deep inside me, in a similar way to DM.
You need to be right on the beat to experience this feeling, even slightly off and it doesn't work.
