金光明經文句記 3.158

3.158

Above, explaining ritual action, it merely causes the three karmas to conform to the Buddha's ordinances, so that once the ritual is completed the offense is eradicated. This is still a distracted mind, so the eradication of offenses is still shallow. Here, discussing obtaining signs pertains to the concentrated mind: when visualization is completed and signs arise, the eradication of offenses is deep. Thus when the visualization of the serpent's mouth is perfected, how could it merely eradicate offenses of sexual misconduct? It also causes lustful thoughts not to arise.
