"To me self-originated/arising is just non-afflictive dependent orgination.
The phrase dependent orgination is not used because DO, in classical Buddhist doctrine, is often used to explain the afflictive 12-linked model that initiates from ignorance to explain the cause of suffering.
When mind is free from the 3 sphere of subject-action-object, free from all elaborations, there is no conceptual delineation, no separation nor union, there is only pure appearances fully exerted as self-arising wisdom.
Dzogchen separates consciousness into "mind" and "wisdom". Mind is dualistic, conceptual and afflictive whereas wisdom is non-dual, non-conceptual and pure but both are consciousness. It is just a more elegant way for the purpose of teaching and provides more clarity otherwise it becomes confusing to explain the cause of suffering. Same goes for DO and self-arising wisdom. Tsongkhapa and chinese buddhism esp just use DO to explain. That is how I see it."
