"Vajra-Muh is a specific type of invocation: muh means to deceive or to blind. Maha, i.e., the blinding, comes from the same root. A moha mantra is the memorized formula for blinding, i.e., it effects what is spoken: blinding. This invocation vajra-muh, causing blinding, is a moha mantra, a spell-binding word. It is used by adherents to blind the demons who could imperil the sacred exercise, shielding the yoga practitioner from the influence of demons."
