Adventitious stains

Adventitious stains (Tib. གློ་བུར་གྱི་དྲི་མ་, lobur gyi drima, Wyl. rigpawiki glo bur gyi dri ma) — ‘adventitious’ means something that is not intrinsically part of us. The implication is that as the ‘stains’ of the four obscurations are not an intrinsic part of our buddha nature, it is therefore possible to purify ourselves of them.
