this song does what all Vedic mantra does, what I’d argue all yogic techniques do: it has a surface or superficial meaning, but if we are given this mantra through lineaged oral tradition we are also re-enacting, incorpoating, or discovering within ourselves a truth that goes down so deep the superficial meaning blanches. There is a process involved in studentship, in other words, that takes you from one kind of understanding to something completely other. This process is lost if folks google their way to enlightenment.
