But you're a PhD candidate!! How can you not have read those kotis of text? Surely the Prajnaparamita must have attempted to find some emptiness to upadana in order to transcend it?
Sorry, I could not resist the lame attempt at humour.
Could I trouble you to take a look at the 法樂比丘尼 (MA 210) and see if this particular sutra discussed upadana and the pancupadanakkhandha with the same term. Would it be 盛 ?
Many thanks in advance.
