摩訶止觀 3.208

There is also that which is indeterminate without being the killing of people: for instance, when cultivating the uncontaminated, the contaminated bursts forth spontaneously without seeking, not killing the two kinds of death at all. If cultivating the middle way bursts forth into the uncontaminated, permanently leaving behind the sea of the suffering wheel of the three realms, this is one death and not the two deaths; this is also termed indeterminate.
