"This mind being by nature clear light, they have seen the poisons to be essenceless and therefore truly realize [the nature of] every being as peace, the ultimate non-existence of a self. They perceive that the Perfect Buddha pervades them all. They possess the understanding that is free from the veils. Thus seeing that beings are utterly pure and that [this purity pervades] their limitless number, they are endowed with the vision of primordial wisdom."
