Bubble of Innocence
The "Bubble of Innocence" is a plasma window (wikipedia/wiki/Plasma_window) that is self generated though years of devout practice of self-control, modesty and respect for one-self. The bubble is commonly achieved by heating up the gas to extremely high temperatures around one-self, AKA being hot, as the plasma becomes viscous other matter has trouble passing through.
